1921 Tachometer Tester | 115V

The Model 1921 Tachometer Tester is used for the testing and calibration of electrical and mechanical tachometer generators and indicators, specifically handheld models. Two variable-speed brushless motors eliminate the need for gears while providing for a testing range of 10 to 50,000 RPM. Each motor/shaft is controlled by a closed-loop system utilizing hall/encoder feedback and a digital motion control card. The result is a very reliable system with a speed accuracy of 0.005%.

The control panel consists of an LCD backlit display with keypad entry, illuminated power switch, emergency stop button, and a shaft rotating indicator.

This 1921 Tachometer Tester (EDMO# 230440-2) is a 115V unit.
