Gasoline Engine Tachometer
SE-2500A - Ono Sokki
SE-2500A is a non-contact handheld tachometer designed for gasoline engine measurement. Detection, measurement, and display parts are all in one unit and batteries are built in the unit. Moving the detector (head of the SE-2500A) close to an ignition coil can measure rotation speed at the unit of 1 r/min or 0.01 r/s. Up to 20 measurement data can be stored in the internal memory that is convenient for later checking.
