The 8 Best RPM Measuring tools (2023 reviews)

The neiko rpm measuring tool should be able to handle its purpose and duties with ease. It includes reflective tape that is surprisingly durable. It measures revolutions over a 1-second sampling time and stores them as the last, minimum, or maximum reading. The large and easy to read LCD screen combined with the quick high speed laser beam allows you to get a quick reading up to 99, 999 rpm. The device sends out a beamed laser spot that gets reflected by the tape or any suitably reflective surface. It is easy to use, and comes with a nice storage pouch.

The unit is extremely accurate. It is perfect for setting the idle on mechanically injected diesel motors. It is easy to operate for taking measurement and diagnostic test results.

Why We Like This:

Comes with reflective tape, batteries, etc
Accurate, easy to use and well priced
New and hot release

Best For electric motor: Agptek RPM Measuring tool

Compared with other tool in this category, the agptek rpm measuring tool has a convenient design. It is an inexpensive, easy application device that provides the user reasonable feedback that could warrant the application of more complex measurement tools. It measures the rotations per minute of spinning objects. It is perfect for the weekend or occasional mechanic. It has a wide range of applications including measuring rotating speed of machine, motors, model cars, wheels, lathe for metal or wood cutting work etc.

The reflective tape is easy to use. The kit comes with a meter, soft case, a battery and enough reflective tape for dozens of uses.

Why We Like This:

Works on everything from ceiling fans to fast-spinning rc propellers
Useful for checking electric motor rpm
Inexpensive, fairly accurate, light weight and small enough to fit tight spaces

Best For wood lathe: FITNATE RPM Measuring tool

Buy on Amazon

If you often find yourself scrambling for convenient and suitable tool, fitnate rpm measuring tool is your end point. It becomes handy when you are building your own ebike and need to know the speed of your motor hub without the load. It acts by shining a laser on a piece of reflective tape and counting the number of times the reflection passes through the beam. It would be similar to reflective tape you would put on a bicycle, or jacket to be seen in the dark. It only takes a very small piece ( 1/4” or 5mm to 6mm) to do.

This product is a great quality tool for measuring the rpm's of most anything. It is great for a lawnmower idle and running speed adjustment. The reflective tape makes one revolution when it gets counted by the tach. It is not a lot of features, but if all you need to know is how fast something is spinning, this is your tool.

Why We Like This:

Widely used in industry, machine tool, automobile, lathes and other industries
Kit with reflective tape and batteries really a plus
Compact and lightweight, easy to take with you anywhere

Best For price: Cybertech RPM Measuring tool

Buy on Amazon

Cybertech line of tool come in a pretty wide variety of styles, so you can definitely find one that suits your individual preferences and needs. This unit with direct contact wheel solves problems and works very well with formula to get results needed. It is a physical wheel for surface detection. The contact part of this tach requires that you actual touch one of the tires they give you to the center of the shaft so the tire spins at the same speed as the shaft and it gives a rpm reading from that. The device has a small wheel that you can friction with the belt or the pulley to the pulley of the alternator, also comes with a sticker that you can place in any part spinning of the engine and read it with the infra red light from the device.

This tach does not use feedback from the ignition system so the points do not matter. It works well for a few days and was able to calibrate rpm on a few machines then the next day the unit would read 2000 rpm instead of 100 rpm. The unit shuts off when the button is not pressed and saves readings automatically, reviewing them is possible but a bit awkward with just one button. It is easy to use for when you need the measurement right away and not saved in memory.

Why We Like This:

Extra large 5-digit lcd display, high accuracy of +/- 0
Auto zero adjustment, stores last, minimum, and maximum readings
New and hot release

Best For things: Reed instruments RPM Measuring tool

Buy on Amazon

We would, of course, be remiss if we didn't mention reed instruments rpm measuring tool for daily purpose. This tachometer is very easy to use and has a great measuring range. While you still need to use a reflective tape to allow for the reflection pickup, the laser is so much brighter than white light tachometers. This is ideal for things like measuring the RPM's of a motor, a spinning wheel, etc. The non-reflective area must always be larger than the reflective area.

This unit is powered by a single 9V Battery. This tachometer should detect the speed of any rotating device so long as it has a small piece of reflective tape on the rotating surface. The R7050 also features a digital counter capable of counting moving objects passing through the instrument's field of view and built. It fits the lab supplied bottles with bottles.

Why We Like This:

Makes quick work of setting idle rpm on mechanical diesels and small gas engines
Easy to use and provides quick readings
A fine tachometer for laboratory use
Minimal drips & fits the lab supplied bottles

Best For High reflectivity: Extech Reflective tape

Buy on Amazon

The extech reflective tape has killer features for the price point. A piece of white tape on a dark shaft or flat black tape on a polished silver shaft will give you a reading. It is designed for high reflectivity and will work. It features a last reading hold, min/max, on target indicator, includes 9v battery, and 24 in. It does not provide average RPM only samples.

It reads super high speed jet engine style fans, it reads with reflective tape, it reads white paint, it even reads with correction tape or fluid on one blade. The readings are based on the unit seeing a sharp change in reflectivity on the object in rotation. An added benefit is that the rolls are 2ft long, and last a long time considering you only need a tiny piece to take readings.

Why We Like This:

Complete with 9-volt battery, reflective tape and user manual
One of the best handheld laser tachometers
Large 5 digit lcd display with backlighting

Best With wheel attachment: Extech RPM Measuring tool

Buy on Amazon

The extech rpm measuring tool should be able to handle its purpose and duties with ease. A digital tachometer like Extech’s rpm33 allows you to measure the revolutions of motors and rotating shafts to ensure operating efficiency. It measures pulses and rpms. This rpm meter has a wheel attachment that directly measures surface speed in m / min or ft / min. This digital tachometer also allows you to store and recall up to 10 data sets with 4 parameters (measurement, max, min and average) for convenient future reference.

The Rpm33 handheld tachometer lets you take laser-guided, non-contact rpm measurements from a distance up to 1.6ft (0.5m), so you can safely collect the data you need. It is built with a quartz crystal oscillator so that readings maintain a high level of accuracy. The meter can measure the linear surface speed ( m / min ft / min), so you will need to follow the next procedure.

Why We Like This:

Complete with contact wheel, 9v battery, reflective tape, carrying case, and user manual
One of the new comers and featured product

Best With sensor: Jomuyee RPM Measuring tool

Buy on Amazon

The jomuyee rpm measuring tool is satisfactory and appropriate and fits well with your daily usage. The tachometer ( RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. It runs off of 3 AAA batteries that you will need to supply. The memory button keeps the measurement on the screen for you to record. The display does not have a backlight but has a large LCD segmented display that shows tenths of an RPM at slower speeds. It is built with durable electronic elements and light abs plastic house. It has convertible accessories for different measurement.

There is a battery level gauge and the meter uses 3 AAA batteries which are not included. If you need good approximations, don't want to spend a bundle and can live with being mindful of background lighting then this thing works well.

Why We Like This:

Just 2 buttons to operate the meter, which shows rpm of any rotating object
Large lcd display with clear reading
Very well built on time fast
Automatically store for the max, min and last value
