2X Digital AC Voltmeter Frequency Meter Tester Gauge LED Display Meter 50-500V 10.0-99.9hz Voltage Frequency Meter

2X Digital AC Voltmeter Frequency Meter Tester Gauge LED Display Meter 50-500V 10.0-99.9hz Voltage Frequency Meter Popis

1. The LED AC voltage frequency measuring instrument is mainly used for real- measurement of the AC voltage frequency in the electrical circuit, and uses the LED digital tube display to display in digital direct reading mode.
2. WIDE MEASURING RANGE: Digital AC voltmeter frequency meter can measure voltage of AC 50~500V, frequency 10.0-99.9hz, accuracy is 1% 2 digits, with high working efficiency of 2 times/s measuring speed.
3. NO EXTRA INDIVIDUAL POWER SUPPLY: Voltage frequency meter can directly connect two wires to the tested voltage to measure voltage and frequency without power supply.
4. SUPER SMALL SIZE: With 68x68MM hole size. This voltage frequency meter can be installed anywhere flexibly, compact and convenient.
5. CLEAR AND INTUITIVE DISPLAY: Voltage frequency tester uses a 0.56in LED font size to display the distribution of data in a concise form, so that readers can quickly understand the data.
