The testo 470 instrument is the ideal combination of optical and mechanical rotational speed measurement (RPM). Mechanical measurements can be performed simply by attaching a probe tip adapter or a rotating wheel for contact rotational speed measurement.
Scope of Delivery
testo 470 instrument in a transport case, including adapter, probe tip, SoftCase protective cover, wheels for contact rotational speed measurement, reflectors, instrument batteries, and factory calibration protocol.
