Pocket Tach 99 (PT99) is a digital, battery-powered portable non-contact optical tachometer (red LED), which operates up to 36 inches from a reflective tape target using an LED light source. The ergonomic design allows safe, direct line-of-sight viewing of both the rotating target and the display at the same time while providing a non-slip rubber surface for single-hand operation. Available with NIST Traceable Certificate
*Performance subject to the intensity of ambient light irradiation.
All Pocket Tach Series instruments provide a unique ergonomic design that allows you to safely observe both the display and the rotating target at the same time
Basic non-contact Optical Tachometer
Pocket Tach 99 (PT99) is a handheld precision optical tachometer designed to make noncontact measurements of rotational speeds from 5 to 99,999 RPM at a distance of up to 36 inches [91.44 cm] from a reflective target and at an angle of up to 30° off perpendicular. The unit has the ability to recall maximum and minimum values. The unit can be tripod mounted and locked on for continuous measurements.
