Description
This instrument 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. The optical sensor helps to prevent external disturbances and the active, modulated infrared beam guarantees correct measurements.
For traditional measurement with contact, a mechanical adapter (cylinder, cone or calibrated wheel) converts the rotation speed into pulses which are then measured by the tachometer.
Model C.A 1727 – Cat. #1748.30: Includes hard carrying case, (1) FRB connector, (1) 9V battery, (1) set of (15) reflective strips, USB cable, a printed Quick Start Guide, TachoGraph software and a user manual.
