Feature:

1. 2 IN 1 MULTIMETER: Voltage and frequency can be displayed with different color on the LED screen, red for voltage, green for frequency, which is clear and convenient to read
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 72x72mm panel, 68x68MM hole size. This voltage frequency meter can be installed on 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
