This Digital tachometer is a high quality instrument to measure the Rotational Speed (RPM) with wide measuring range and high resolution.
High accuracy measurement, quick measuring time and long detecting distance up to 500 mm (20" inches)
This Digital tachometer is very easy to use by applying a reflective mark (included in package) on target object,then aim at the mark with the laser tool.
This tachometer has wide range of applications including measuring rotating speed of machine, motors, model cars,wheels, lathe for metal or wood work...
