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. The reflective tape is easy to use. 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.

Best runner up: Digiten lathe RPM GAUGE

Buy on Amazon

The digiten lathe rpm gauge is capable of outshining several other gauge featured in this list in overall features. It is designed for a magnetic (hall effect) sensor only. It includes a tachometer x 1 hall npn proximity sensor x 1 magnet x 1tips. This tach uses a magnet fastened to the rotating shaft, with a pickup that senses when the magnet passes it. The magnet does not fly off and the sensor is mounted close to it. It only has revolutions per second. It is installed on an excelsior mini-lathe refitted with a 3/4 hp variable dc motor from psi. It is great as an auxiliary speed feedback device.

Why We Like This:

Bright enough for day, not blinding at night
An easy and important upgrade to any shop tools which turn a spindle
1000 rpm at idle for most vehicles

Best For wood lathe: Digiten Hall sensor
