The Extech RPM33 Laser Photo Tachometer quickly measures RPM, surface speed and length with one tool. Use the contact wheel
for up-close readings or laser mode for safer, non-contact measurements up to 1.6ft (0.5m) away. The RPM33 has a large 5
digit backlit LCD display. The unit is microprocessor based with quartz crystal oscillator to maintain high accuracy. It
provides wide RPM (photo and contact) and linear surface speed/length (contact) measurements. The non-contact laser can take
measurements up to 1.6ft (500mm).
Applications for the contact RPM include:
Flywheels
Conveyors
Pumps
Elevators
Applications for the non-contact RPM include:
Motors
Fans
Gears
