Tachometer C.A. 1725

C.A. 1725 tachometer 

Easy to handle with numerous measurement possibilities

The C.A. 1725 tachometer allows for the measurement of revolutions in three different ways. In addition to contact measurement through a mechanical cam, the tachometer offers the possibility of non-contact measurement via a modulated infrared signal and reflective bands on the object to be measured. An external measurement input on the tachometer allows for the connection of the signal generator. The measured values are displayed on a large LCD screen.

- Revolution measurements up to 100,000 r.p.m.

- Measurements with or without contact

- Large LCD display with analog bar graph

- Numerous functions, memories, and automation to facilitate information gathering: 

   measurement of rotational speed, linear speed, counter, frequency, and period

- Min. and max. functions.

- HOLD function to freeze measurement values on the screen

- SMOOTH function to filter the measurement; averages the last 10 measurements

- Robust transport case
