The condition monitoring tachometer PCE-T 238 is a battery-powered hand-held device that allows mobile use. The condition monitoring tachometer can perform a contact measurement as well as a non-contact measurement. It is also possible to perform a measurement of the surface velocity. The condition monitoring tachometer allows a measurement of up to 99,999 revolutions per minute. This measuring range is possible with contactless measurements with the optical tachometer.
