REED R7150 Professional Combination Contact / Non-Contact Laser Photo Tachometer


This tachometer features both the ability to measure RPM (revolutions per minute) in rotational equipment and surface speed m/min (meters per minute) / ft/min (feet per minute) with included contact adapters. The built-in laser for non-contact measurement provides accurate measurements up to 6.5 ft (2000 mm) away from target.


  • Dual function unit with both contact and non-contact capabilities
  • Provides fast and accurate RPM measurements of rotating objects and surface speed measurements MPM (meter per min) and FPM (feet per min)
  • Laser provides improved accuracy at a greater distance
  • Internal memory recalls min/max and last value
  • Large LCD Display reverses depending on measurement mode
