DC Ammeter LED Display 50A Hall Sensor Current Gauge for Auto

1 Easy Calibration: This meter adopts exquisite SMT technology, so it has good consistency. It is equipped with current calibration potentiometer and zero adjustment potentiometer. If there is any error, you can calibrate it yourself. 2 Simple and Safe Operation: The current sensor adopts a through hole design, and the wire directly passes through the hole. The current measurement can be realized without damage or changing the original current circuit. 3 Isolated Design: Because the current sensor is completely electrically isolated from the measured wire, this meter can measure the current of the positive pole, negative pole of the power supply, a certain line at will. The voltage withstand value between the measured wire is up to 2KV. 4 Forward and Reverse Current: Ammeter can measure the forward and reverse current of the line, display the positive current in the forward direction (the decimal point of the ammeter is always on or off), and display the negative current in the reverse direction (the decimal point of the ammeter flashes slowly). 5 Wide Applications: Equipped with two wires to facilitate access to solar energy system, car, battery car and motorcycle lines, timely grasp the charging and discharging status of battery, and can also be used for other purposes.
