Handheld Digital Laser Photo Tachometer RPM Tach Small Engine Motor Speed Gauge;

This is a great handheld Digital Photo Laser Tachometer with a large LCD display. It can measure the rotational speed of machine parts, engines and motors in RPM, revolutions per minute, with a visible light beam. The RPM measurement is contact free, that means you can measure from a safe distance and you will not slow down the rotating shaft. Just attach a reflective sticker to the rotating part and point the red laser beam on the mark from a safe distance. It is a great tool to measure the RPM of motors and machine parts. In wood and metal working it can be used to accurately measure the speed of a lathe, drill and router. HVAC technicians use it to measure the speed of fans and electrical motors in heating and air conditioning systems. This laser tachometer works on a standard 9V battery with more than 100 hrs of battery life! We now include a strip of our super reflective tape!
