Cigarette lighter tachometer model:HAD-1581

Brief introduction

HAD-1581The engine tachometer measures the electrical noise signal reflected on the battery during engine operation, which is amplified by the circuit,After filtering, it is sent to the intelligent systemCPUAnalyze and judge, collect useful signals,And use specific algorithms to obtain engine speed. measurable3 、4 、6 、8The speed of a four stroke cylinder engine is suitable for gasoline, diesel, and natural gas engines. Widely used in motor vehicle environmental testing institutions, automobile repair shops, manufacturing plants and other departments.

2、 Product Features

1 High testing accuracy, fast acceleration or deceleration tracking speed.

2 High adaptability and measurability of vehicle models>9 5 %.

3 Multi core processing system for more accurate testing and dynamic switching.

4 The connection with the vehicle is simple and reliable, only the cigarette lighter socket or battery end of the engine can be connected for measurement. It is both a power supply and a signal acquisition point, without human interference.
