The KH140F color screen wireless bluetooth battery coulomb counter is a professional instrument for monitoring the remaining battery capacity.

At the same time, it can monitor the battery voltage, current, power, ambient temperature, electrical energy, the time required for full charge and the amount of energy during charging and discharging.

A series of parameters such as how long it takes to support 0-400A current, and can be used for batteries with a voltage of 0-120V in a fully charged state.

All of the following parameters can be accurately monitored:

  • Voltage
  • Current
  • Temperature
  • Power
  • Watt-hour
  • Amp-hour
  • Remaining Capacity
  • Endurance Time
  • Charging Time

Performance advantages:

  • The 2.4-inch high-definition color screen, the color matching is beautiful and generous, and the font is larger and clearer;
  • Provide a mobile phone APP, which connects to the meter via wireless Bluetooth to view data and set parameters;
  • The mobile APP can view the real-time curve and historical curve of voltage and current, and historical data can be exported;
  • The display and measurement module are connected through a 3m 4P co-directional telephone line, the longest can be extended to 30 meters, which is more convenient to install;
  • Both shunts and screws are made of pure copper materials to minimize power consumption in standby mode;
  • After configuring the relay by yourself, it can realize over-voltage protection, under-voltage protection, over-current protection, over-temperature protection, and over-power protection.
  • The mobile phone APP can upgrade the wireless firmware of the measurement module;
  • The parameters of voltage, current and temperature can be calibrated by themselves;
