The Amprobe TACH20 hand-held tachometer accurately measures rotational or surface speed as well as length. Measurements are displayed on a large, easy to read LCD. The meter also includes an integral memory function that permits automatic storage of maximum, minimum, average values plus the last measurement displayed.

Amprobe TACH20 tachometers are designed with optimal mechanical stability to ensure accurate, reliable and repeatable measurements. A variety or measurement units and mode functions can be selected. Contact rpm measurements are made by using the surface speed wheel. Non-contact measurements are made via the infrared beam.
