Tachometers

HH100 - Electro-Sensors, Inc. (Electro-Sensors, Inc.)

The HH100 Hand-Held Digital Tachometer combines both contact and non-contact sensing to accurately measure RPM, surface speed, and length. When using the non-contact mode, rotational speed (RPM) is measured using a visible beam of light. The HH100 can be up to 14 inches away from the small piece of reflective tape that is affixed to the rotating element.
