Contact Instrument Solutions

Available to buy is the Testo 470 tachometer with SoftCase (protective case) in transport case, adapter, probe tip, surface speed disc, reflectors, batteries and calibration protocol. Optional calibrations are available.

Non-contact and mechanical rpm measurement. The instrument has the ideal combination of optical and mechanical rpm measurement. Reflectors are attached to the object being measured during optical measurement.

The visible, red modulated light beam is directed on the reflector. An optical becomes a mechanical measurement by simply attaching an adapter and cone or running wheel.
