Application report - Service / Maintenance of pumps with digital hand-tachometer redpoint


The speed of a pump driven by an electric motor has to be checked on a weekly basis in accordance with an internal quality guideline.

A calibrated, non-contact measuring system, which is able to measure the speed precisely, is required for this purpose.


With the digital hand-tachometer redpoint, the speed is measured very precisely by reflecting a bright beam on an affixed reflective strip.

The hand-held digital tachometer is supplied with a DKD calibration certificate. Annual recalibration is also possible.
