CHAUVIN ARNOUX – Infrared Tachometer C.A 1725

Category:

With its rotary switch, the C.A 1725 is simple to use and offers numerous measurement possibilities with or without contact.

Measurement by photo-reflection for no-contact measurement: a reflective strip is positioned on the part to be tested.
Contact measurement with accessories: a mechanical adapter (cylinder, cone or calibrated wheel) converts the rotation speed into pulses which are then measured by the tachometer.

The digital display shows a 42-segment bargraph, the functions selected, the alarm thresholds, etc.
The rotary switch gives direct access to 7 different measurement units (RPM, Hz, etc.) and each key on the keyboard corresponds to a function (MIN MAX, Smoothing, alarms, etc.).
