We compared these with our calibrated and certified Lutron DT2236 and the results came out exactly the same so you are getting a very accurate tachometer for a good price.
A great tool to measure the revolutions per minute of shafts, pulleys, wheels, blades, centrifuges etc without losing a finger.
TO USE
Stick a short piece of the self adhesive reflective tape (supplied) to the shaft, pulley or wheel etc to be measured (while stopped!). Press the side button and aim the laser at the reflective tape. The current rpm will be displayed and will update if the rpm changes.
