Application

This is a great Digital Photo and Contact Tachometer that gives 3 measurement options in one meter, photo or laser measurement, contact measurement and surface speed measurement:
a.Laser Photo (non-contact)
b.Rotational Speed (contact)
c.Surface Speed (Contact)

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. Other people use it for their model engines and propellers
