HT100 Hand Tachometer

The HT100 Hand-Held Rate & Time Indicator’s display provides a highly visible reading, even in dim light or at indirect viewing angles.

When used as a non-contact indicator, a marker (reflective tape, supplied) is placed on the shaft, or other target that is to be measured. The HT100 is then simply pointed at the marker to read rate-per-minute, seconds-per-event, or counts. An in-contact adaptor is provided that allows display of linear feet or meters per minute, RPM, or counts.

  • Complete kit – includes Hand Tachometer, in-contact adaptor, carrying case, and reflective tape
  • Microprocessor circuit allows switch selection of rate, time, or counting modes
  • High contrast LED display can be easily seen in dim or shadowed lighting conditions
  • Measures speeds from 3 rpm to 99,999 rpm
