• Instant Voltage Monitoring:AC 80-300V digital voltmeter with flat US plug displays live voltage values on its LCD screen. The blue backlight enhances visibility in low-light conditions.
• Low Energy Consumption:Operates on less than 1W power (1kWh per 1200 hours) for continuous 110V-220V circuit tracking. Compact plug design fits tightly against wall outlets.
• Precision Calibration:Internal adjustment potentiometer enables accuracy tuning: Rotate counter-clockwise for overvoltage or clockwise for undervoltage using a screwdriver.
• Versatile Application:Designed for home appliances, office equipment, and industrial sockets. Avoid use in damp areas.
• Dual-Function Display:Combines clear voltage readings with soft backlighting that doubles as ambient illumination in dark spaces.
