Mechanical Hour Meter: Suitable for a wide range of applications including engineering machinery, agricultural equipment, generators, air compressors, water pumps, cranes, and various types of vehicles. Enables accurate tracking of total operating time. Efficient Time Tracking: Operates on DC 10–80V with an internal mechanical gear mechanism for real-time monitoring of cumulative working hours from 0 to 99999.9 hours, with 0.01-hour accuracy. Provides irreversible and precise time recording. Data Storage: Automatically retains recorded data when power is disconnected. Timing resumes from the last accumulated value, ensuring continuous and reliable data tracking. Durable Design: Features a sealed construction with a wide operating temperature range of -10°C to 50°C. Offers effective anti-vibration performance (10–70 Hz, 1.8g), ensuring long-term reliability in demanding environments. Compact and Low Power: Designed with a compact form factor and low power consumption of 0.3W, making it ideal for accurate time measurement in industrial applications.
