Feature: 1. SAFE MATERIAL: Coulomb meter adopt excellent industrial grade ABS with impact resistance and high temperature resistance. PVC flame retardant material shell, safe and reliable 2. ACCURATE AND LOW CONSUMPTION: The shunt and screws are made of copper material, possess good electrical conductivity and low heat. Low power consumption, standby state will not consume too much battery power. As small as the gasket springs are all made of copper to ensure more accurate sampling accuracy 3. CONNECT TO MOBILE PHONE: Open the Bluetooth connection to view all relevant data and curves on the for wechat mini program, and support to set parameters and operate related functions through the for wechat mini program 4. DISPLAY PARAMETERS: This is a multi functional coulomb meter, which can display voltage, real time current, real time power, remaining capacity, and multiple physical parameters in real time. Using 12864 LCD, the display data is comprehensive and clear 5. APPLICABLE SCENARIO: The voltage current coulomb meter is used to monitor the output voltage and current, and charge and discharge batteries Specification: Item Type: Battery Capacity Coulomb Meter Material: ABS Specification: 120V 500A.
