The 5 Best Digital tachometers (2023 reviews)

The agptek digital tachometer's material feels more premium than its price would suggest. This device measures the rpm of a physically rotating / spinning object and that can have the included reflective tape attached to it. It works well and is able to measure reliably over a good range of speeds. The laser is pointed at the reflective material and counts the revolutions of the rotating ( reflective) part. It comes with reflective tape that you put on whatever you want to check the speed on. 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 reflective tape is easy to use. It has a wide range of applications including measuring rotating speed of a machine, motors, model cars, wheels, lathe for metal or wood cutting work etc.

Why We Like This:

Very handy and useful for many applications
Useful for measuring the angular velocity of a fidget spinner
Delivers what they promise

Best For High reflectivity: Extech Digital Tachometer

Buy on Amazon

The extech digital tachometer is specially designed for your daily usage and has all useful features. It is a class ii laser product, with 1mw power output. 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.

This unit shows the very last sample. It does not provide average RPM only samples. It features a last reading hold, min/max, on target indicator, includes 9v battery, 24 in. It is easy to read in dimly lit environments. It is used for greater accuracy and longer measuring distance.

Why We Like This:

One of the best handheld laser tachometers
Complete with 9-volt battery, reflective tape and user manual
Mini laser photo tachometer, noncontact, rpm range 2 to 99, 999, accuracy +/-

Best With sensor: is Digital Tachometer

Buy on Amazon

We would, of course, be remiss if we didn't mention is digital tachometer for daily purpose. 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 has ac voltage in and does not need a transformer to power it. It is easy to assemble, but requires soldering three wires to connect the hall sensor to the three-pin connector. The sensor has a lot of length adjustment for an easy installation. The ability to plug 120VAC directly in saves the cost of a Walwart or Brick power supply.

The magnet should be isolated from the metal background to improve the magnetic field between the magnet and the sensor. It is allows for precise monitoring of the speed, even in low-light conditions.

Why We Like This:

Minimize the use of strong electromagnetic devices to avoid interference
Good brand reputation

Best For RPM Measurement: Kaisal Digital Tachometer

Buy on Amazon

The kaisal digital tachometer should be able to handle its purpose and duties with ease. The Digital tachometer provides a variety of units for you to choose from.
