A tachometer is an instrument which measures the working speed of an engine, or any rotating object, typically in revolutions per minute.

The digital tachomter model ETM 400 D is a versatile device to monitor the r.p.m. of any rotating object without any physical contact. It can adapted for event counting apart from r.p.m measurements.

Accurate monitoring of r.p.m. has made ETM 400D tachometer a popular choice in sugar, paper, and textile industries.
