461893 CAL

The 461893 CAL from Extech Instruments is a non-contact digital photo tachometer. This device provides non-contact measurements over a wide range (5 to 100,000RPM). A reflective mark on the object to be measured is used as a target for the meter's integral light beam. With this device, user can make non-contact RPM measurements (5 to 99,999RPM) of rotating objects by pointing the integral light beam (6inch target distance) at reflective tape placed on the object to be measured. The memory button holds last reading and recalls min/max readings display. Careful use of this meter will provide years of reliable service.
