3-in-1 Digital Voltage and Frequency Meter Generator (System)

【3-in-1】This 3-in-1 device simultaneously tracks AC voltage, frequency, and cumulative run time, simplifying generator maintenance.
【Dual Time Tracking】Dual time tracking records both cumulative engine hours and the duration of the current session, helping you accurately schedule oil changes and monitor fuel consumption per task.
【Bright LED Display】The 4-digit digital tube LED display provides crystal-clear readings in direct sunlight or on dimly lit jobsites, preventing misreadings during critical operations.
【Self-Powered Installation】The self-powered installation draws its power directly from the measured circuit, with no external battery or wiring modifications required, for a stable and clutter-free dashboard.
【Dual Voltage Versatility】Available in 220V and 380V AC configurations, this dual voltage versatility is designed for industrial backup power units, portable construction site generators and agricultural power systems.
