Here you will find many types of rotation meter. There are different ways of measuring revolutions within the industrial sector, either optically or mechanically. The PCE-151 handheld series of rotation meter with RS-232 interface can measure revolutions and velocity and store the readings onto a computer using software which comes with the device.

The handheld digital rotation meter is ideal for measuring velocity and revolutions in research and maintenance. The PCE-T236 rotation meter measures velocity both by contact and non-contact and is good value for money. Non-contact measurement of velocity is done with the help of reflective tape.
