Pocket Laser Tach PLT200

The rugged and versatile Pocket Laser Tach is ideally suited for non-contact, contact
and linear speed measurements.

Pocket Laser Tach 200 (PLT200) is a digital, battery-powered portable optical
tachometer, which operates up to 25 feet (8 meters) from a reflective target using a
class 2 laser light source. The er gonomic design allows safe, direct line-of-sight viewing

of both the target and the display at the same time, while providing a non-slip rubber
surface for single hand operation.

Multi-Function For Pro-Active Maintenance

PLT200 is a 32 function Tachometer/Ratemeter, Totalizer/Counter and Timer
(stopwatch), which is programmable in both Imperial and Metric rates. Two phono

plug connectors for our optional Remote Contact Assembly (RCA) or remote sensors.
The PLT200 also has a TTL compatible pulse output to trigger devices like vibration
data collectors or stroboscopes. The KIT is supplied complete with a Remote Contact
Assembly including concave and convex tips and a 10 cm linear speed wheel all in a

latching carrying case.
