REED R7140 Combination Contact / Laser Photo Tachometer

Dual function tachometer features the ability to measure RPM with non-contact (visible light) and contact (ft/min / m/min) measurements quickly and accurately.

This tachometer features both the ability to measure RPM (revolutions per minute) in rotational equipment and surface speed m/min (meter per minute) / ft/min (feet per minute) with included contact adapters.

The R7140 uses visible light for non-contact measurements to read up to 12" (300mm) from any target. It features a durable ABS plastic housing to assure years of maintenance free performance.

 Features:          (Replaced Model K4010)

  • Automatically holds last reading for 5 minutes and recalls minimum and maximum readings
  • Characters on the 5-digit display reverse direction depending on which measurement mode you are in
  • Microcomputer LSI circuitry provides accuracy to 0.05% and permits readings to a resolution of 0.1 RPM in either photo or contact mode
  • ABS plastic housing assures years of maintenance free performance
  • Designed to fit comfortably in either hand
  • Includes: 3 contact adapters (2 cones, 1 funnel), surface speed wheel, reflective tape, batteries and hard carrying case
  • NIST Traceable Certification Available
