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. In the contact operating mode, the speed is sensed by directly contacting the rotating device using one of the contact adapters supplied with the instrument. In other applications where surface or linear speeds are to be measured, the universal wheel is used for direct readout of feet/min, meters/min, or inches/min, as selected by the end user.

The HH100 can also be used to measure the accumulated total of continuously running material such as paper, wire being wound on a spool, or to check the calibration of on-line counters and totalizers.

The HH100's rugged construction, portability and outstanding features make it an ideal choice for maintenance personnel, machine operators or others in a wide variety of machinery and material handling applications.

The HH100 uses the latest microprocessor technology and is backed by an industry leading, two-year warranty.
