We’re always excited about the first product on our list! After all, this did every product we’ve tested, by now. Here, we’re talking about the Hardline Products HR-8061-2 Tachometer. And, yes, we love it! 

From a unique point of view, this product is capable of providing 16000 RPM readings. Isn’t that a great thing? If you’re unaware of this, it’s better when the tachometer provides RPM readings over 10000 RPM. So, the higher, the better! 

Besides, it’s not usual for any tachometers to get a higher RPM reading. If you get one, it’ll provide the results! 

But, the path to get towards reading needs to be easier too. Here, the Tachometer comes with 3 inputs that are adjustable. You can even set the idle speed if you want to. And, the best part is that you can set the input through your touch. 

When it comes to compatibility, this tachometer has the ability to work on “2 cylinders 24 stroke engines”. You can even use them on the engines with fuel injections.

That’s not all. This device has the ability to work on FI bikes. We’ll leave you with the judgment if this is a great thing or not. 

Now, all of the results will be shown on the display. So, that needs to be better as well, right? Good news! The product has a better-than-average display. It comes with the ability to display records for up to 1000 hours. 

You can take readings from the saw at any time and the display will record it. But, you might wonder about the batteries and their lifespan. You don’t really want to waste money changing them over again? 

It doesn’t matter really. The batteries inside the box last you for 10 years. And, you won’t even need to replace them. Hence, money saved. 

Face it! You’ll have to work around chainsaws for some time with this device. And, it isn’t a nice place to work on. Working with chainsaws means you’ll need to go around dust, water, and even waste! 

Hence, the durability needs to be in check as well, right? Well, the good news here as well. The product is made of high-quality materials that’ll provide superior toughness. So, that won’t be a problem either. 

Besides, it’s made of a 100% epoxy encapsulated case. Therefore, water will certainly not damage the outer shell. Speaking of water damage, it even has an IP 68 rating.

So, it’s waterproof, alright! We’ve tested it ourselves and love the water and dust-proofing. 

The last thing you should know is that it’s pretty easy to install and comes with a wire of 14 inches. Even though it’s expensive, the price is justified due to the added benefits! So, your call!

No products found.

  • RPM Capacity: 25,000 RPM
  • Accuracy: 10 RPM
  • Weight: 52 Grams
  • Dimensions: 2.24 x 1.42 x 0.67 inches

The last product, we’ve bragged about how much RPM capacity it came with. And, if we have your attention to this factor, you’ll love the Searon Digital Chainsaw Tachometer. So, let’s check out what you’ll get and what you won’t- 

The first thing out of the way is the 25000 RPM. We’ve spoken about how important a higher RPM number should have! Guess what? This product provides a wider range of RPM readings starting from 0 to 25000. Also, it maintains an accuracy level of 10 RPM.

Now, comes the topic of compatibility issues! Well, you can use the tachometer with chainsaws and other gas devices. Plus, lawnmowers, bikes, boats, and tractors can use this device too. So, you have your options here. 

Overall, this device is known for its wider application. Yes, you can use it from V8 engines to single cylinders. 

Another impressive thing about this product is the incredible runtime! Here, it comes with 99999 hours of runtime. At least that’s what they claim it to be.

But, we did test things out! Frankly speaking, it’s not as much as they claim. 

Let’s give an idea about the usability of this device. Heads up! Things are pretty simple. Firstly, you’ll need to hold the on/off button down. Then, the display icon will show “off”. Then, you’ll have to release that button. 

After this, the meter will turn off. Next, you have to press the button again in the same manner. In this manner, the display will turn on. Also, you can program inverted timers again from 0-200 hours. 

As we’re on the topic of usability, let’s talk about another feature in this device. The tachometer comes with a flash alert system that’ll work at enhancing usability. 

Compared to the previous product, this one powers CR2032 lithium batteries. Unlike the other AAA batteries, it powers with 3 volts. Just install the battery and it’ll run for a lifetime. 

But, it’s no sunflowers here. We have some complaints here with the batteries. The overall installation feels a bit clumsy. It’s easier, don’t get us wrong. But, it’s not the most comfortable thing, let’s get that out of the way. 

Other than that, it’s an easier product to recommend. It does bring a lot of benefits. So, we’ll leave you with the choice. 

3. Cyber-Tech Digital Photo Laser Tachometer

No products found.

  • RPM Capacity: 2.5 – 99,999 RPM
  • Accuracy: +/- 0.05%
  • Weight: 9 Ounces
  • Dimensions: 4 x 1 x 6 inches

Yeah, we know color isn’t everything. Heck, color isn’t a deciding factor in a tachometer. But, this product does put a smile on our faces due to the lavender color. Let’s see what there’s in store here- 

Yes, the lavender color is the unique thing about this product. Quite a neat design, I must say! Also, there’s an RPM capacity of 2.5-99999 RPM. And, it even maintains an accuracy level of +/- 0.05%.

Besides, the options you’ll get from this product are quite good too. Here, it’ll work with anything that rotates. You can use it for HVAC applications to calculate fan rotation.

Unlike the previous one, this digital tachometer runs on 4 AA batteries, and it can read between 2.5 to 99,999 RPM. The accuracy level of this calculation is near around .04-.05%, which deserves kudos.

On top of that, there is an auto-zero adjustment feature that can store the values that you want. Furthermore, the CyberTech Digital Photo Laser Tachometer features a solid LCD display. Instead of regular, cheap-quality displays, you get a vibrant and colorful LCD display. 

In conclusion, all we can say is that the cyber tech digital photo laser tachometer deserves a spot in our review simply because of its feature set. You should certainly try it out.

But, we do believe the ratio of price with performance could’ve been improved! Other than that, it deserves our support.

No products found.

  • RPM Capacity: 20000 RPM
  • Accuracy: 1 minute
  • Weight: 80 Grams
  • Dimensions: 2.64 x 1.38 x 0.69 inches

Who isn’t into technology these days? If you’re into that kind that loves fiddling with technical features, we present this one. The Runleader HM032R Inductive Tachometer is clearly the best wire chainsaw tachometer on our list! 

The best part of this product- it can read both hours runtime and the RPM of an engine or chainsaw. The hours reading is up to 99999 hours, and the RPM reading is up to 20,000 RPM.

Now, let’s give you an idea about how you can actually measure the RPM of the chainsaw. To start off, you have to connect the wire to the device and view the display. That’s all there is to it. 

As we’re on the topic of the display, it’ll be quite unique by its greenish background and dark numbers. This increases the overall visibility in a different way of course. 

Furthermore, it’ll make things quite easier to view the data at night time as well. It can’t get any easier if you want to know how to use a chainsaw tachometer. 

You’ve seen us brag about the runtime. And, why shouldn’t we? The CR2032 battery with the Runleader HM032R Inductive Tachometer combines at providing the best runtime. 

In terms of price point, the tachometer is also a winning pick as well. We hope that you’ll keep it on your shopping list. 

Now, let’s nitpick about this product for a bit. We love this part! But, we don’t love the fact that this tachometer comes with hard-to-press buttons. 

Due to this factor, many people complained about how their fingers hurt and all. Well, it isn’t that hard to hurt your fingers. But, it’s quite an annoying factor. So, thumbs down, from our facts! 

5. Neiko 20713A Tachometer

No products found.

  • RPM Capacity: 2.5 – 99,999 RPM
  • Accuracy: +/- 0.05 %
  • Weight: 8.8 Ounces
  • Dimensions: ‎6.85 x 4.33 x 2.01 inches

We were happy with the 20000 RPM on the previous product. Now, let’s take things to the next level. The RPM capacity of this tachometer is 99999 RPM! Isn’t that a charming thing? Let’s begin, on this note- 

The best thing about this product is the RPM capacity range. Here, you’ll get a 2.5 – 99999 RPM range.

It even has an accuracy percentage of +/- 0.5%. But, the unique thing is the laser aim operating technology. It can calculate the speed. And, it even takes measurements from a 2 – 20 inches distance.

We call this one the easiest-to-use tachometer! But, how? Well, we already spoke about how it uses the laser aim operating technology, right? It even makes it easier to make calculations from a distance. 

And, you’ll see the results from a large display too. Here, you are getting a 5-digit LCD display, which has acceptable viewing angles. 

For non-contact measurements, there is also a 24-inch reflective tape in this meter. This will make your measurements and design better as a whole. 

Another great thing about this device is the weight. Even though this isn’t a deciding factor, it’ll work fine. The device is very lightweight to use. 

All you have to do is to keep an eye on the charge of AA batteries that it runs on. And it will keep you serving until a lifetime. 

So, everything about this tachometer is the best, until this point. There’s a thing we don’t like and we fear you might not like it as well. What’s that? 

When you’re working with chainsaws, you’ll need to look at a lot of factors. Out of them, environmental factors are quite the thing! As this tachometer doesn’t have waterproofing on it, we fear it could get damaged easily. 

Yeah sure, take good care of it and make sure it doesn’t go near water. But, waterproofing in this device would’ve been much more appreciative. At least that’s what we believe! 

6. Searon Digital Tach Hour Meter Tachometer

No products found.

  • RPM Capacity: 25,000 RPM
  • Weight: 80 Grams
  • Dimensions: 0.08 inches

Bringing in another product to our list. We’re almost at the end, though! But, there are things to focus on here. Let’s begin- 

We’ve always loved the Searon Digital Hour Tachometer. For the small engines, this is quite the option. This digital hour meter and tachometer combo will keep a sharp eye on the running time and the RPM value of the engine constantly. 

The best part about this one is the display. When the device/engine is on, it will read the RPM. And when it’s off, it will show you the hour runtime of the engine or the chainsaw.

With the results we’ve tested, we could say it’s quite accurate. The capacity of calculating the RPM goes up to 25000 RPM. Plus, you can calculate the hours up to 99999 hours! The accuracy of this data is around 10 RPM and 0.01 hours. So, yeah, it’s quite accurate! 

Like any other good quality tachometer, this Searon Digital Hour Tachometer has also got an internal CR2430 battery inside. It’ll power up its operation and ensure an extended lifespan. To be precise, you can expect a lifetime of up to 1000 hours. 

The design is made to be completely waterproof, and that’s a quite guaranteed feature from the end of the manufacturer. The IP-68 rating is proof that your device will stay out of harm from water or rough weather conditions. 

Compared to the previous product, it has a better waterproofing ability due to its rating. But, it isn’t that durable, to begin with. Here, the product comes with a flat design. As a result, it isn’t that tough to start. 

And, for working around chainsaws, you need a durable and tough device. Sadly for this product, it isn’t the thing to be impressed about. 

But, we still loved the accuracy and RPM range. It’s quite easy to use. But, the durability factor is a thing to be considered. 

7. Timorn Tachometer For Small Engine

No products found.

  • RPM Capacity: 99,999 RPM
  • Weight: 50 Grams
  • Dimensions: 2.05 x 1.81 x 0.79 inches

The last one’s the charm! Or, is it? We’re here with the Timorn Tachometer. This plastic is quite accurate, don’t get us wrong. Even though it’s at the lowest in the barrel, there’s a lot to talk about. Let’s go on then-  

The internal battery is the most impressive thing about this product. It comes with 35000 hours of operation rating! Quite a bold claim. Well, it did live up to the expectations. We’ve tested it. Also, you can replace the internal battery. So, that’s a bonus too.

Now, let’s think about what devices you can use with this product. Even though the tachometer has the name of being a small engine, it can work with different devices. 

Here, a two-stroke or four-stroke gasoline engine is able to be equipped with this tachometer. In case you want to use it on a chainsaw, that would also be a perfect use of it.

No matter if it’s the engine or chainsaw, it will be able to show RPM values up to 99,999. 

Now, the installation factor! To install the tachometer on your device(engine or chainsaw), you don’t have to go through any hardship at all.

It’s an easy-to-install device where you are going to use it. So, the usability is on point. 

As it’s a wired tachometer, there is a 1.9-meter-long wire along with the device. And to operate with it in full swing, you will be provided with an intuitive user’s manual as well. 

We’ve spoken about the great things about this batter. Here, it comes with a CR2450 Lithium battery. It will provide a lifetime of battery backup to keep your chainsaw tachometer operated. 

Overall, it’s a pretty solid option for any user considering the price and usability. You can’t go wrong with it. But it did miss out on some key factors. So, bummer right there. 

RPM Range: How Much?

Well, well, you’ve seen how much RPM range the tachometers provide. We’ve even seen ridiculous numbers of 99999 RPM from different brands. Don’t sweat, you don’t need this much for your chainsaws. 

After all, the range shouldn’t be this high. If you want our advice, the 10000 RPM range would be just fine. So, if you get tachometers that provide a lower RPM range, see whether they’re at 10000 or not. 

That said, we’d always appreciate a higher RPM range. So, the ones providing 30000 RPM range get the upper hand too. But, we still believe that the 99999 RPM range is quite ridiculous. But, hey, you might wanna show off, who knows? 

Build Quality

As you’re working with chainsaws, the durability of the tachometers is an issue. After all, you want devices that’ll last for a long. Otherwise, they’ll break down easily. 

Normally, we’ve seen plastic tachometers in the list. They’re great as they keep the weight down at all times. But, they’re not durable enough, we believe. These devices need to be durable. 

In this case, the ABS tachometers are far far better. We tested their durability and found positive results. Hence, durability is an issue you need to consider if you want your tachometers to last for a while. 

Waterproofing Ability: Is It Important? 

Yeah right! We’ve spoken about this factor too. Is it important, however? Yes, it’s quite important. After all, your tachometers will be exposed to water, dirt, and debris. 

Hence, it needs all the waterproofing there is! Yeah sure, you can keep your tachometers away from water. But, you’ll never be sure of all the circumstances. 

Yes, the tachometer could get damaged with a slight splash of water in the display. Hence, it’s more than important that it’ll have the best waterproofing ability. Otherwise, it won’t last for long. 

Power Delivery System: Which One’s Better? 

Some chainsaws take AAA batteries to power up their devices. Whereas, the others require CR2450 batteries to power up. 

As we’ve tested out both batteries, we believe the CR2450 is more powerful than the usual AAA battery. It just provides an added kick/boosts to increase the lifespan of the product. 

So, you might want to choose your desired power delivery system before even buying the tachometer.

How You Can Use a Tachometer for Chainsaw Tuning

Using a tachometer for chainsaw tuning can be a helpful way to ensure that your chainsaw’s engine is running at the correct RPM (revolutions per minute).

Proper tuning is essential for optimal performance, fuel efficiency, and longevity of the chainsaw. Here’s a step-by-step guide on how to use a tachometer for chainsaw tuning:

  • Get the right tachometer: First, you need to acquire a tachometer that is compatible with small engines like chainsaws. There are various handheld tachometers available in the market that can measure RPM accurately.
  • Read the user manual: Before you start tuning your chainsaw, familiarize yourself with the tachometer’s user manual. Different models might have specific instructions on how to use them correctly.
  • Prepare your chainsaw: Make sure your chainsaw is in good working condition. Clean the air filter, check the spark plug, and ensure the chain is properly tensioned and lubricated.
  • Locate the spark plug: To measure the RPM accurately, you’ll need to connect the tachometer to the chainsaw’s spark plug wire.
  • Connect the tachometer: Some tachometers come with a clamp-style sensor that can be attached to the spark plug wire. Others might require you to insert a wire into the spark plug boot to read the signal. Follow the tachometer’s instructions to establish the connection securely.
  • Start the chainsaw: Start the chainsaw’s engine and let it warm up for a few minutes to ensure stable running.
  • Measure the RPM: With the chainsaw running at idle, point the tachometer at the spark plug wire or the wire inserted into the spark plug boot. The tachometer will display the RPM reading.
  • Adjust the idle RPM: Consult the chainsaw’s user manual or the manufacturer’s recommended RPM settings for idle. If the idle RPM is too high or too low, adjust it using the chainsaw’s idle speed adjustment screw until it matches the recommended value.
  • Measure full throttle RPM: Next, rev the chainsaw to its maximum speed (full throttle) and check the tachometer reading. Compare this reading with the manufacturer’s recommended maximum RPM for your chainsaw model.
  • Adjust the high-speed mixture: If the full-throttle RPM is too low or too high, you might need to adjust the high-speed mixture screw on the carburetor. Refer to the chainsaw’s user manual for the correct procedure to adjust the carburetor settings.
  • Recheck and fine-tune: After adjusting the idle and high-speed settings, recheck both the idle and full-throttle RPM readings. Fine-tune the settings if necessary to ensure they match the manufacturer’s recommendations.
  • Safety first: Always prioritize safety while tuning your chainsaw. Wear appropriate safety gear, work in a well-ventilated area, and keep the chainsaw’s chain away from any obstructions while tuning.

Frequently Asked Questions

What needs to be done when the tachometer isn’t accurate?

You may be facing what we like to call ‘tachometer jumping’. It’s a problem where you may get less reading than the usual reading you’re supposed to get. So, check the tachometer connections for good measure. 

What does that imply- the readings are in the red region?

When you’re using a manual tachometer and the needle gets into the red region, you may have some issues with the chainsaw. You may want to consider slowing down the RPM rating to get better longevity out of the machine. 

How does the inductive tachometer operate?

When it comes to the principle of an inductive tachometer, then you may see a rotating shaft that’s got a wheel with teeth. As you put the measuring point on the outside of the wheel, the tooth comes around and alerts the sensor. That’s how you get the RPM readings. 

What is a common fix for malfunction?

You could always change the fuses to get accurate results. 

Final Verdict

Done! We’ve shown you our secret list of the best chainsaw tachometer in the market. As we’ve nitpicked about all of the products, we’re confident about you making the right judgments.
