HM-1 Hour Meter

Product Overview

Based on ATST Electric’s core concept of “Precise Control, Safe and Reliable”, HM-1 Hour Meter is developed for accurate recording of equipment running hours in industrial and commercial electrical systems. When the connected equipment is powered and operating, the meter accumulates working time automatically, helping users understand actual equipment usage.​

HM-1 adopts a mechanical counting structure, providing stable and intuitive runtime display without complex programming. It is especially suitable for equipment that requires regular maintenance, operating-hour statistics or lifecycle management.​

With multi-voltage compatibility, compact panel installation and low power consumption, HM-1 can be widely used in generators, air compressors, motors, pumps, production machinery and other equipment where long-term operation monitoring is required.​

Main Features

1. Accumulated running time recording: Automatically records the total operating hours of connected equipment when power is supplied.​

2. Mechanical counting structure: Provides stable hour accumulation and clear visual reading, suitable for long-term industrial use.​

3. Multi-voltage adaptability: Supports multiple voltage options for different electrical systems and equipment control circuits.​

4. Power-on timing mode: Starts timing when the equipment is energized, making operation time tracking simple and reliable.​

5. Low power consumption: The product is designed with low operating power, suitable for continuous connection in electrical systems.​

6. Compact panel installation: Practical size design allows easy installation in control panels, machine housings and equipment cabinets.​

7. Maintenance management support: Helps engineers plan preventive maintenance, service intervals and equipment replacement based on actual operating hours.​

Application Scenarios

1. Generator operation monitoring: Used to record total running hours of diesel generators, standby generators and power generation equipment.​

2. Air compressor maintenance: Suitable for tracking compressor operating time and arranging oil changes, filter replacement and routine servicing.​

3. Motor runtime recording: Applied to motors, fans, pumps and rotating equipment for usage statistics and maintenance planning.​

4. Industrial machinery: Used in machine tools, production equipment, conveyors and processing machinery to monitor accumulated working time.​

5. Pump systems: Suitable for water pumps, circulation pumps, drainage pumps and irrigation pumps requiring operating-hour records.​

6. HVAC and ventilation systems: Applied to air conditioning units, exhaust fans, cooling fans and ventilation equipment for service management.​

7. Equipment lifecycle management: Helps factories, workshops and maintenance teams evaluate equipment usage, reduce unexpected downtime and improve maintenance efficiency.
