Review on 🔍 BAFX Products Handheld Infrared Tachometer - Accurate Non-Contact Digital RPM Meter for Measuring Rotational Speeds by David Dortch

Bought to set up a zero turn mower. You have to adjust the speed of each rear wheel driven by hydraulic motors. I glued a reflective tape to each rear wheel, picked it up and started. Checking the speed of each rear wheel. The tachometer takes a minute to stabilize its readings. They could be set with an accuracy of 1/2 rpm. Good work. Ask two earth magnates to make reflective dots for use on other metal objects, it will be easier than using strips of reflective tape. Basically, I am satisfied with the devices.
