Runleader HM032R Inductive Tachometer is a great place to start. It is an induction tachometer intended for 2 or 4 stroke gasoline engines. The system displays up to 99999 hours/20000 RPM, so there is quite a bit of room to run.

This model has a replaceable battery, and the data is stored automatically after you replace the battery. The tach hour meter can show the current RPM even while the engine is running.

The LCD display screen is backlight and easy to read. The induction wire measures at 1.5M, and the whole device has a waterproof rate of IP65. The RPM measuring system measures the current RPM, records and shows the engine’s max RPM, and has a setting that can warn the user of over speed so that the user can adjust accordingly. Whether you are just checking your instrument or seeking to make adjustments, having multiple methods of measuring is helpful.

The operation of the hour meter is connected by five feet of insulated wire, so there is plenty of room to work.

The timing system includes several different features. The total running hours that are counted are non-resettable, however, the partial running time can be reset as you change jobs. The maintenance timer can be set freely.

The carburetor adjustment tool is the addition you didn’t know you needed! This is a tool that can be used on most engines and is essential for frequent tune-ups and adjustments.

STIHL EDT 9 Chainsaw Tachometer

Last but certainly not least, this is the STIHL wireless latest model. It is specialized to be used as both a wireless and a wired option, depending on your needs. It is used specifically to measure the idle speed and the top speed of chainsaws, or other outdoor equipment.

This device works with single or dual magnet flywheel systems and is also intended for 2 or 4 cycle engines. A flywheel system is an energy storing system and has to do with conducting and transmitting kinetic energy.

This is the most expensive option in comparison to the other models listed in this article, so that is worth mentioning. However, the reviews online are all positive it works like a charm and gets the job done.

In comparison to other options, it isn’t nearly as available as other options to the general public both to buy, or to research! There is very little information online, and even fewer options of where to find or buy it. So, if this is the model you want, get ready for a treasure hunt.

At the time of this research, there aren’t stats listed online for this product. So other than what is listed above, there isn’t any way to know what the capacity or capability of this device is.

We aren’t sure what kind of battery it takes, whether it is replaceable, or what kind of wires it uses. None of that means that this is a bad option, however, it does mean that we are less informed regarding what other benefits this device could offer.

The Ultimate Buyer’s Guide: What Do I Need To Know?

So, you have had your crash course in which tachometers to consider when you buy one. But if you are new to the world of small engines, why are tachometers so important, and what else do you need to know?

What Do Tachometers Do?

Tachometers measure the speed of a rotating engine, or, the RPM of an engine.

What Does RPM Stand For?

RPM stands for rotations per minute.

Why Are RPMs Important?

Knowing how your piece of equipment is functioning is helpful information to know whether or not it is functioning correctly/up to par. Depending on how your chainsaw has been used, if its equilibrium has been thrown off, it may not be functioning as well as it could be.

Why Use a Tachometer?

A tachometer shows the rotation of the engine we’ve covered this already. If a tachometer shows the rate of rotation of the engine, this measurement can be compared to the safe range of rotations for the individual instrument to make sure it is functioning properly.

Should I Need to Alter My Tachometer at All?

Some tachometers may have a longer wire than what you need. If that is the case, you can cut the wire’s excess so that it fits your individual instrument better.

What Else Do I Need?

You may need a screwdriver to get to the right place in your chainsaw, however, the most important thing you need is the user manual and/or specification sheet for your chainsaw. If you do not have this, you will not know where the speeds should sit.

Setting the speeds incorrectly could cause your saw to overheat and burn out, so you must be careful with the adjustments you make and ensure that they are right for your device.

Are There Different Kinds of Tachometers?

Some models will clip or wrap a wire around the spark plug wire. Some newer, digital tachometers will not need a physical connection in order to record RPMs. They all do the same work, but they collect information differently.
