Features ???? FLAME RETARDANT: The energy meter integrates screwless CT wiring to prevent poor contact and heat generation, non-contact testing is safer. pc flame retardant, high temperature resistant, non-flammable. ???? CONVENIENT INSTALLATION: The digital voltmeter adopts the standard distribution installation, 35mm rail slot installation is more convenient. ???? LIQUID CRYSTAL DISPLAY: The voltage and current meter tester adopts a large screen liquid crystal display, the reading is more clear. Data display format is clear, high precision, easy to read. ???? EASY TO USE: Multi-function current and voltmeter has stable performance, high precision and accurate test results. It is a convenient and practical voltage and current tester. ???? WIDELY USED: Ammeter-voltmeter is widely used in high and low distribution cabinets, electronic maintenance, photovoltaic inverters, home circuit measurement and other fields.
