Key Product Features

1. 100-250VAC Ultra-Wide Input Voltage, Global Universal
   Adapts to unstable grid voltage in rural, mining and overseas regions, compatible with all single-phase 220V/230V generator output voltage, no voltage transformer required for direct wiring use.
    
2. LCD Digital Clear Display + Power-off Memory Function
   Intuitive hour-minute digital display, easy to read data even in dim environments; built-in storage chip, cumulative running hours will not be cleared after shutdown or power failure, accurately record the total service life of equipment.
    
3. With Hidden Reset Button, Flexible For Maintenance & Rental Management
   The rear hidden reset key can manually reset timing data, convenient for equipment overhaul, rental equipment billing statistics, batch maintenance cycle management, solving the pain point that traditional mechanical hour meters cannot be cleared.
    
4. Fully Sealed Industrial Dustproof & Waterproof Structure
   Integrated sealed shell effectively blocks dust, water mist, oil pollution and vibration interference, avoiding meter failure caused by dampness and mechanical jamming, suitable for long-term outdoor and engine compartment harsh working conditions.
    
5. Simple Two-Wire Wiring + Standard Panel Fixed Installation
   Only live wire and neutral wire need to be connected, no polarity requirement; standard two-hole mounting hole spacing, directly replace old mechanical hour meters, no need to modify the control cabinet installation hole position, quick on-site maintenance replacement.
    
6. High Precision Quartz Timing Chip, Stable & Low Failure Rate
   Timing error ≤±0.01 hours, long-term continuous operation without time drift; low power consumption design, no extra power consumption burden for equipment control circuit, stable and durable.
    

Common Equipment Failures Solved

• Old mechanical hour meter is easy to get stuck, mis-count or stop timing, unable to accurately record equipment running hours, leading to missed maintenance cycles and engine wear damage
• Non-resettable hour meter cannot clear data, inconvenient for equipment rental billing, factory overhaul and secondary equipment commissioning management
• Ordinary hour meter only supports narrow voltage range, easy to fail under unstable grid voltage in remote areas
• Open-type instrument shell easily enters dust and water vapor, resulting in short circuit and black screen failure in humid pump room and engine compartment
• Complicated multi-wire wiring of traditional timers increases hidden dangers of line short circuit and virtual connection
