Sonic Tachometer ST-01

Sonic Tachometer ST-01 is used for measurement of the rotation speed of the single-cylinder internal-combustion engine spindle (rotations per minute – RPM) and registration of the maximal values during the defined periods of time with the ability of recording them in a non-volatile memory for reviewing later. The measurement is conducted by the analysis of the spectral components of the acoustic vibrations emitted by an operating engine.
