It measures Revs Per Minute.
Just stick a small piece of reflective tape to the device you want to measure, point the Digital Laser Tachometer at the target whilst its spinning, and its tells you how fast (in Revs Per Minute) the thing is turning.
It also tells you the min an max Revs Per Minute
You need something reflective on the moving object
great for checking small motors
I use this for checking the Revs Per Minute of small electric motors that students have built to check out there efficiency.
Works well for the price.
