Wholesale of calibration devices for motor vehicle engine speed measuring instruments for sale

This product adopts an integrated design, with a built-in vibration table, large capacity lithium battery, and printer; The data from the mining speed measuring instrument is automatically detected, minimizing manual repetitive operations.

This product is used for measuring and calibrating the speed measurement instrument of motor vehicle engines. Currently, it can measure and calibrate five types of tachometers.

Voltage pulsation type:A tachometer that extracts engine speed signals through a car cigarette lighter or battery;

Low frequency vibration type:A tachometer that measures the low-frequency vibration signal generated by the engine's work.

Engine detonation type:A tachometer that measures the high-frequency vibration signal generated by the combustion moment of an engine.

Gasoline ignition type:A tachometer that senses the ignition pulse signal of a gasoline engine.

Diesel fuel injection type:A tachometer that senses the fuel injection pulse signal of a diesel engine.

Execution standard: Calibration specification for motor vehicle engine speed measuring instrument "JJF1375-2012"
