Applications

Widely suited for landscaping machinery (lawn mowers, garden tractors), engineering and road equipment (excavators, loaders, road rollers), the automotive and marine industries (passenger cars, commercial trucks, ships, yachts), and various electrically powered devices such as generators, compressors and water pumps that need precise electric timekeeping to manage equipment maintenance and monitor operational hours.

Tips: How should different hour meter types be selected?

Hour meters can be selected based on timing method, power compatibility, and environmental requirements. Electric hour meters record time only when electrical power is supplied, making them suitable for electrically driven equipment, while engine-run or vibration types are often used in fuel-powered machinery. Voltage range should match the system to ensure stable operation, and installation style affects ease of integration. In harsh or outdoor environments, waterproof and durable designs are preferred to ensure long-term, reliable runtime tracking for maintenance planning and equipment management.
