RPM40 Laser Photo/Contact
Pocket Tachometer
Convenient pocket-sized combination tachometer,
quickly measures RPM and Linear Surface Speed.
Use the contact wheel for up-close readings or
laser mode for safer, non-contact measurements up
to 4.9ft (1.5m) away. Characters on display reverse
direction depending on measurement mode used.
Applications:
• Contact RPM - flywheels,
conveyors, pumps, and
elevators
• Non-Contact RPM - motors,
fans, and gears
Features
• Large 5-digit LCD where characters on display reverse
direction depending on measurement mode you are in
• Microprocessor based with quartz crystal oscillator to
maintain high accuracy
• Provides wide RPM (photo and contact) and Linear
Surface Speed/Length (contact) measurements
• Laser guided for greater distance non-contact
measurements up to 4.9ft (1.5m)
• Memory stores Max/Min/Last readings
• Complete with cone tip and wheel for rpm or
linear surface speed, four 1.5V AAA batteries, and
reflective tape
