465 – RPM Meter

With the Testo 465 tachometer, you can perform non-contact rpm measurement using just one hand. This makes the tachometer suitable, for example, for measurements on rotating parts such as fans and shafts. To measure the rpm, simply stick a re ective marker on the measurement object, aim the visible red beam at the marker and measure the rpm. The distance between the tachometer and the measurement object can be up to 600 mm.
