50A DC Digital Ammeter With Hall Sensor - LED Display Current Gauge For Car, RV, Motorcycle Battery Monitoring

About This Product

Keep an eye on your vehicle's electrical system with this handy 50-amp DC digital ammeter. It uses a non-invasive Hall effect sensor—you just run the wire you want to monitor through the hole in the sensor (up to 50 amps), and it measures the current without you having to cut or splice the wire. It's fully isolated, so it's safe to use on positive or negative lines. The bright red LED display (0.52 inches) shows you the current flow in 0.1-amp increments, and it can show both charging (positive) and discharging (negative) current. It needs a power supply between 4V and 30V DC (like from your vehicle's accessory circuit) and has calibration pots on the back if you ever need to fine-tune it. The whole unit is small (about 2.1 x 1.2 x 0.8 inches) and fits in a standard dashboard or panel cutout. Perfect for monitoring alternator output, battery drain, solar panel charging, or any other DC current in your car, truck, RV, boat, or motorcycle. Know exactly what's happening with your power.
