The REED R7200 is a pistol-grip LED stroboscope built for freezing and measuring the motion of rotating or reciprocating machinery without contact, covering a wide 60 to 99,999 FPM/RPM range at a very fine +/-0.001% accuracy. It uses 16 bright LEDs for the flash source, offers a 5-digit display with selectable FPM or Hz units and internal phase-shift capability, and runs on a rechargeable 7.4V lithium-ion battery good for around 8 hours of continuous use.
