DROK 0.39" Current/Voltage Tester, DC 4.5-100V Digital Multimeter, 0-50A Voltage/Ammeter, Red and Green Dual LED Display, Car Panel

Affordable Wiring & Tight Design: The DROK Tester Multimeter features three wiring terminals, so when testing voltage and current, power comes directly from the circuit, eliminating the need for an additional power supply. Despite its compact size (70mm x 40mm x 30mm), this meter can simultaneously display voltage and current. Wide Measurement Range: The multimeter has a wide measurement range (voltage measurement range: DC 4.5-100V; current measurement range: 0-50A). Note: To minimize error, it's recommended to test currents above 20A. Additionally, this meter features voltage and current calibration potentiometers. If there's any error, you can adjust it yourself. Common Ground Design: The DROK Digital Volt-Ampere Meter features three wiring terminals. When testing voltage and current, power comes directly from the circuit, eliminating the need for a separate power supply. Strong Anti-Interference Capability: The current voltage monitor boasts strong anti-interference capabilities, allowing for a fast display refresh rate. Crafted with exquisite SMT technology, it offers excellent consistency. This ammeter voltmeter panel has a shell that is safe, reliable and dustproof. Wide application: DROK DC voltmeter ammeter has convenient connection and wide application, for example, it can be applied to monitoring changes in voltage and current status of storage batteries, DC adjustable power supplies, or other devices.
