Description

The HHT21A combines the accuracy and safety of a noncontact laser tachometer with the convenience and ease of operation of a pistol grip instrument. Simply aim the tachometer at a reflective tape target on the rotating object, squeeze the trigger, and read the RPM. The HHT21 has both internal laser optics and the ability to be used with a remote optical sensor. It may be handheld or mounted utilizing the ¼-20 threaded bushing in the base of the handle.
