Kkmoon 2.4 Inch Wireless Voltage Meter Ammeter Voltmeter Coulometer Battery Power Detector Battery with waterproof cover

This is a multi-function instrument based on 2.4G wireless data transmission technology, which can display various physical parameters such as voltage, current, power, capacity, energy, temperature, running time, etc. in real time. Battery charge and discharge management and over-voltage, under-voltage, over-current protections accompanied by buzzeralarm. Moreover, the instrument uses a 2.4-inch color LCD as a display, which displays more comprehensive, clear and easy-to-observe data. Features: Wireless transmission of data to avoids interference caused by complex wiring between the display and the detection module. The Hall sensor is used to realize non- detection of current, without breaking the line, safer, reliable and convenient. Voltage, current, power, temperature, capacity, percentage of remaining capacity, and running time are displayed at the same time. Reserve interface for charging and discharging double relays, 5 relay working modes can realize automatic disconnection and automatic closing of charge and discharge. With charge overvoltage, discharge undervoltage, charge overcurrent, discharge overcurrent protections, over temperature protections function, low temperature protections function, with buzzeralarm prompt function. With power-off memory function, it can record the number of AH and WH before power-off. When charging, the percentage progress bar is switched to the color running water light display, and the display screen shows the breathing light flashing effect, which enhances the prompt. With voltage, current, temperature waveform curve display function. Chinese and English language selection, two display colors can be switched, suitable for different customer needs. Specifications: Type: with waterproof cover, without waterproof cover (optional) Input current measurement range: 0.4-300A Language: Chinese/English Screen size: 2.4in Capacity measuring range: 0-99999.9AH Energy measuring range: 0-5999.9KWH Time measuring range: 0-100H Power measuring range: 0-999KW Temperature measuring range: 0-150Celsius Measurement rate: 20 times/sec Relay delay time: 0-100S Display board size: 80 * 48 * 17mm / 3.1 * 1.9 * 0.7in Measuring board size: 114 * 54 * 28mm / 4.5 * 2.1 * 1.1in Package size: 250 * 175 * 65mm / 9.8 * 6.9 * 2.6in Package weight: 411g / 0.9lb Packing List: 1 * LCD Monitor 1 * Measurement Module 1 * USB Cable 1 * User Manual 3 * Connecting Line
