Mini 2-in-1 Digital Voltmeter Ammeter, 22 mm, Round

This is a mini style voltage & amperage all-in-one meter/monitor. It only needs a 22mm round mounting hole for installation. Different than other voltage gauges on the market, MVR-22R will be self-powered when connecting to a testing circuit (50 ~ 500V AC), and it does not require any external power supply. Instead of using a shut, an AC current transformer (inductive transducer, included) is used for more accurate reading and easier installation.

MVA-22R has two-line display. Top line is for voltage reading. Bottom line is for amperage reading.
