Battery Tester Voltmeter Ammeter Battery Coulometer Capacity Indicator Description: The KG-F series color screen wireless bluetooth battery coulomb meter is a professional instrument for monitoring battery power. It can also monitor the voltage, current, power, ambient temperature, and energy of the battery during charging and discharging. And display how long the battery can be fully charged in real time, how long can the remaining battery power be used. KG110F measuring current range is 0-100A, KG140F measuring current range is 0-400A, KG160F measuring current range is 0-600A; lead-acid batteries, Lithium iron batteries and all other batteries with voltages of 0-120V can be used in the fully charged state. Specification: Model: KG110F, KG140F, KG160F (optional) Voltage measuring range (external power supply): 0-120V Voltage measuring range (self-supplied): 10-120V Voltage resolution: 0.01V Current measurement range: 0-100A, 0-400A, 0-600A (optional) Current resolution: 0.01A, 0.1A, 0.1A (optional) Relay: optional Temperature range: -20-120℃ AH range of measurement: 0-9999.99AH Bluetooth communication distance: 10m Voltage accuracy: ±2%+3 digits Current accuracy: ±5%+10 digits Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-3mm measuring deviation due to manual measurement.
