Testo 470 Dual Function RPM  Tachometer

The testo 470 dual function tachometer is the ideal combination of optical and mechanical rpm measurement.

Non-Contact Optical Measurement: easily measure rpm by simply attaching a reflector to the object to be measured, point the visible, red light beam at the reflector and measuring.

Mechanical Measurement: an optical measurement becomes a mechanical measurement by simply attaching an adapter for a probe tip or surface speed disk.
