KETOTEK Digital AC Voltmeter Panel Mounting Meter AC80-300V Frequency Counter 45.0-65.0 HZ LED Display Voltage Volt Frequency Meter Tester Gauge

2 in 1 MultimeterVoltage and frequency can be displayed with different color on the LED screen, red for voltage, green for frequency. It is clear and convenient to read.
Wide measuring rangeVoltage: AC 80~300V, Hertz: 45-65Hz, Accuracy: 1% ± 2 digits, with high working efficiency of 2 times/s measuring speed.
No extra individual power supplyIt can directly connect two wires to the tested voltage to measure voltage and frequency without power supply.
Ultra small size2.68×1.65×1.5inch / 68x42x38mm. This Voltage Frequency Meter can be installed on anywhere flexibly.
More informationOperating temperature: 10°F~122°F/-10 ~ 50. Note: The AC current meter only suits for pure AC 50-60HZ power supply and can NOT be used for square wave, inverter output and sine wave circuit measurement of modified sine wave, otherwise the meter will be damaged.

Technical Indicators:
