Tachometer Speed Calibration Test Meter

A tachometer speed calibration test meter is a device used to test and calibrate the accuracy of tachometers. Tachometers are instruments used to measure the rotational speed of a machine or engine. Tachometer speed calibration test meters typically work by generating a known rotational speed, which is then measured by the tachometer under test. The tachometer speed calibration test meter then compares the tachometer’s reading to the known rotational speed. If the tachometer’s reading is within a certain range, then it is considered to be calibrated.
