Product Description
Digital AC Voltage Frequency Meter, DROK Digital Voltmeter Panel AC 80-300V 110v 220v Frequency Counter 45.0Hz-65.0Hz LCD Display Voltage Frequency 2-in-1 Monitor Tester Gauge with Two Wires
- DROK 2 in 1 meter can measure AC Voltage 80-300V and frequency 45.0-65.0Hz simultaneously, with potentiometer for frequency calibration, turn the screw clockwise to increase frequency and turn the screw anticlockwise to reduce the frequency.
- The panel meter can directly connect two wires to the tested Voltage to measure Voltage and frequency without offering power supply.
- Our digital voltmeter can test voltage with high accuracy and high working efficiency of 2 times/s measuring speed.
- Only suitable for Pure ac45-65hz Mains supply, can't be used for measuring circuit of square wave, inverter output and sine wave.
- Two wires direct connection, standard installation Size, can work under extreme environmental condition.
