Reviews Ac Frequency Counter

Proshopping Digital AC Voltage Frequency Meter, AC 80-500V Voltmeter 45-65Hz Frequency Counter, LED Display Voltage Gauge, Mini Volt Hz Monitor Tester, High Voltage Panel Indicator -for Generator, RV

  • 2 in 1 AC voltage frequency meter - can automatically detect and display the accurate real-time voltage (V) and frequency (Hz) simultaneously.
  • Universial volt Hz monitor - wide voltage measuring range AC 80-500V.
  • high working efficiency of 2 times/s measuring speed.
  • Sensitive digital LED screen display - the small voltage dectector with a upgrade clear and bright LED display, better than LCD.
  • Easy to use - 2 wires design, just connect directly with your device, it can test automatically, without extra power supply.
  • can embedded buckle installation, more stable.
  • Multifunctional application - Only suitable for Pure AC45-65Hz mains supply, can't be used for measuring circuit of square wave, inverter output and sine wave. (It can't be used for measuring the AC power converted from a DC power with an inverter).
  • perfect for different modes of gasoline engine generator, diesel engine generator, motor and RV.
