Baomain Voltmeter DH-670 AC 0-30V Rectangular Class 2.5 Analog Panel Volt Voltage Meter

Hooked this up to my thermostat to indicate if heat is being called.

Great meter, smoth movements, easy to read, just what was needed for the train layout.

I bought a few of these for custom monitoring of 120v or 240w power systems. It's nice to see if the current is drifting up or down. I like analog meters rather than digits wandering up or down.

Looks good, and is reasonably accurate.

Item arrived on time and in new condition. I've yet to install it in the intended device, but a preliminary test with a DC adapter shows it accurate at 9 and 12 volts, so so far, so good.

It was the correct size for a tube tester I was fixing. A little hocus pocus on the shunt resistors and it was converted to a 5mA current meter. A graphics program took care of the meter face

very good product.

I purchased two. Thinking the first one i ordered was bad. I ordered a second one. Both do not work. I applied 0-30 volts ac to the terminals on the back and neither worked. I tested voltage at source and at terminals with a digital and an analog meter and both meters read voltage. I Returned and received two replacement meters. Both worked. Must not have been my lucky week.

reads 30+ on a 24V setup
