I am building a panel to monitor power input and output on a rotary phase converter. This meter sold on Amazon (DROK 0.39 Inches LED 2in1 Multimeter AC 500V 200A Voltmeter Ammeter, AC Volts Meter Panel Ammeter Gauge with Current Transformer, 2-Wires Digital Ammeter Volts Meter Tester https://www.amazon.com/dp/B01M8LCWNW/ref=cm_sw_r_cp_tai_ulrCEb7JET4SG) would work well for size, but I need something capable of measuring and displaying volts/amps to at least 1 decimal place in accuracy (0.1V, 0.1 Amps). Do you have a similar size and design product with that capability?
