It works well and is able to measure reliably over a good range of speeds. It is a high quality instrument to measure the rotational speed (rpm) with wide measuring range and high resolution. It will work on any system that has a rotating component that is accessible to its laser beam and that can have the included reflective tape attached to it. The laser is pointed at the reflective material and counts the revolutions of the rotating ( reflective part. It is used to check rpm on a home made gas pressure washer pump.

The compact, lightweight design of this photo tachometer makes it easy to get speed readings for diagnostic and measurement purposes. It includes a custom protective cushioned storage case, 3 AA batteries, instructions and a. The sensor in the tach picks up the pulses and performs the measurement, displaying in 0.1 RPM steps for speeds up to 999.9 RPM, and 1.0 RPM steps from 1000 to 99999 RPM. It comes in along with the reflective strips.

The body of tachometer is slim and easily fits into the palm of your hands. The device sends out a beamed laser spot that gets reflected by the tape or any suitably reflective surface. It has a min and max RPM function, showing the variations in the speed of the measurement.

Why We Like This:

Accurate, easy to use and well priced
Comes with reflective tape, batteries, etc
Has a memory option which remembers the last set of readings

Best With phone: Digiten RPM Measuring device

Buy on Amazon

The digiten rpm measuring device's high-end materials makes sure that it ages well with use. It is perfect for a vehicle electrical system. It includes it works using the magnetic input from a single magnet. The magnet is attached to the rotating shaft and the pickup is located in close proximity to read the rotations per minute. It is installed on an excelsior mini-lathe refitted with a 3/4 hp variable dc motor from psi. The display is green but the sensor(pickup) has a tiny red led that will flash every time the magnet passes the pickup to show you its reading the revolutions. The magnet is very strong. You can use any small neodymium magnet with them, a stronger one will give you a larger usable gap.

Bright enough for day, not blinding at night
One of the new comers and featured product

Best For price: Cybertech RPM Measuring device

Buy on Amazon

The features department is where cybertech rpm measuring device truly manages to shine. This unit with direct contact wheel solves problems and works very well with formula to get results needed. It can only measure the rotation of a shaft or the speed of a conveyor belt using a wheel. It is used to touch on a conveyor belt to show belt speed. It will measure rpm, m/min, but not meters or feet as distance traveled. The accessories are obvious, easy to connect, even the slivers of reflective tape.

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. Love accuracy, and this device with features and optional accessories is a great device to add to your tool box.

Why We Like This:

Auto zero adjustment, stores last, minimum, and maximum readings
Extra large 5-digit lcd display, high accuracy of +/- 0
Delivers what they promise

Best With Shopsmith mark: is RPM Measuring device

Buy on Amazon

The is rpm measuring device might be a relatively new release, but it's still nothing short of impressive this year, thanks to multiple price cuts and added new features over the past few months. This affordable digital tachometer is a great addition to any machine. It comes with a hall sensor and magnet, ensuring excellent stability and accurate hall induction for reliable speed measurement. It is used to meter to monitor the rpm. It is easy to install and works very good. The board converts this to whatever DC voltage is needed for the Hall effect sensor and display. It is easy to assemble, but requires soldering three wires to connect the hall sensor to the three-pin connector.

The magnet should be isolated from the metal background to improve the magnetic field between the magnet and the sensor. It is great for adding on to a lathe or drill press.

Why We Like This:

Minimize the use of strong electromagnetic devices to avoid interference
Delivers what they promise

Best tool: Jomuyee RPM Measuring device

Buy on Amazon

We would, of course, be remiss if we didn't mention jomuyee rpm measuring device for regular usage. 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. It's a great tool to have when judging new equipment. The display does not have a backlight but has a large LCD segmented display that shows tenths of an RPM at slower speeds. It comes with batteries, so you'll have to have 3 AAAA batteries.

The memory button keeps the measurement on the screen for you to record. It'll tell you where it's at right now, and there's a memory button to show the fastest speed it read. It's easy to use, very accurate at fast speeds.

Why We Like This:

Very well built on time fast
Low battery indication function, data hold function, powered by 3 * aaa batteries
Large lcd display with clear reading
Just 2 buttons to operate the meter, which shows rpm of any rotating object
