Linkstyle DC 5V-100V & 100A Digital Amp Voltage Meter, Dual Display Current Voltage Meter Gauge with Hall Effect Sensor Transformer

2 in 1 Voltage & Current Meter: This amp voltage meter monitors both real-time voltage and current in one device, eliminating the need for separate meter, red indicates voltage, green indicates current

Wide Measurement Range: This voltage gauge measures DC voltage from 0V-300V and current from 0A-100A with ±0.1 accuracy. Get precise, real-time readings to ensure stable power use and prevent overloads

Through-hole Measurement: The voltmeter ammeter with Hall effect sensors can measure bidirectional currents, regardless of direction. Note: decimal point indicates negative current

Multiple Protection & Reset Function: The built-in smart chip safeguards against short circuits, overcurrent, and overvoltage. Even if wired incorrectly, the device remains protected. Additionally, the reset button allows for easy calibration—press for 3 seconds to reset, or 6 seconds to restore to factory settings

Universal Application: The digital voltage supports 5V-100V DC systems, making it suitable for cars, trucks, RVs, motorcycles, boats, solar power setups, battery packs, and other low voltage equipment
