Introduction:
- This is our newly developed boat engine hour meter. Compared to our old version circular quartz hour meter, it has a built-in red rotatable gear that rotates slowly when powered on, allowing users to easily and clearly understand its working status.

- Its standard operating voltage range is 12-36VDC/AC, so it can meet your maintenance and usage needs regardless of whether your marine engine is equipped with a 12VDC, 24VDC, or 36VDC battery.
- In addition to the operating voltage mentioned above, its operating voltage can also be customized to 10-80VDC/AC, so if your battery is 72VDC, you can use it freely. You can contact us for customization.
- The usage is very simple. Simply connect this time gauge to the ignition switch, and it will record the machine’s running time once the device is started. The wiring diagram is as follows:
- In addition to marine engines, this mechanical hour meter can also be used in construction machinery, engineering vehicles, agricultural machinery, generators, air compressors, water pumps, bridge cranes, elevators, and various types of automobiles.
