Review on πŸ”Œ KETOTEK AC Voltmeter Panel Mounting Meter AC80-300V Frequency Counter 45.0-65.0 HZ LED Display Voltage Volt Frequency Meter Tester Gauge by Michael Colley

Revainrating 5 out of 5

Don't guess the power of your home generator.

I bought this to test the output voltage and frequency on my newly installed backup generator. I tested the unit by plugging it into a 120 volt household outlet powered by our utility company. The displayed frequency was 60.0/59.9 Hz. The voltage was 122 volts, which was confirmed by my digital fluke meter. This is actually more accurate than I had hoped. Very satisfied.

Pros
  • Top marks for support and durability from testers
Cons
  • Unbelievable price
