Hour RPM meter counts the hours, based on alternator signals, the signal is mostly taken from ‘W-Point’ and indicates the corresponding Engine rpm. Incorporated hour meter shows true engine hours. Suitable for most petrol and diesel engines. Very accurate and stable indication due to micro controller based aircore movement. LCD hour counter and back light provided for clear visibility at night condition. Hour counter starts counting when the speed of the engine reached above idle rpm.

Hour counter counts and displays the time of the vehicle or machine has been used. Suitable for all machines and all types of vehicles.Highly accurate and stable hour counting with microcontroller based design.
