DT-2236C Digital Laser Photo Tachometer Speed Gauge Contact and Non-contact Tachometer

Description: 
This digital tachometer is a high-quality instrument using non-contact ( photo ) and contact method to measure the rotational speed ( RPM ) and surface speed with wide measuring range and high resolution.This tachometer is very easy to use by applying a reflective mark ( included in the package ) on the target object, then aim at the mark by Laser beam. It has a wide range of applications include measuring rotating speed of motors, model cars, wheels, lathe for metal or wood cutting work etc..
