Handheld Contact and Noncontact Laser Tachometer

The HHT13 is a digital, batterypowered portable optical pocket laser tachometers, which operates up to 7.6 m (25') from a reflective target using a laser light source. The ergonomic design allows safe, direct line-of-sight viewing of both the target and the display at the same time, while providing a no-slip rubber surface for single hand operation.

The HHT13 is a 32 function tachometers/Ratemeter, Totalizer/Counter and Timer (stopwatch), which is programmable in both English and Metric rates. Support is built-in for the optional Remote Contact Assembly (RCA) and the plug-in Remote Sensors. The HHT13 has a TTL compatible Pulse Output to trigger devices like data collectors or stroboscopes.
