Electronic Specialties 332 Lazer Photo Tachometer

The #332 is the ideal tool for easy and accurate measurement of RPM in almost any environment. Simply aim the laser beam at a reflective mark placed on a rotating device, push the button and the RPM reading is immediately displayed. No contact with the shaft or wheel is necessary. The laser beam is not affected by shop light and can detect RPM from longer distances of up to 6 ft. away. The #332 can measure up to 99,999 RPM in 1 RPM increments. It can be used to measure RPM on coil-on-plug and diesel engines, where conventional inductive tachometers can not be used. Other uses include generators, compressors, industrial engines, fans, gears and more. Zippered case, reflective tape, instructions and 9V battery included.
