Measuring voltage 0-120V,measuring capacity 0~9999.99AH; Applicable to batteries, such as ternary lithium batteries, lead-acid batteries, lithium iron phosphate batteries, etc.; 2.4-inch high-definition color display, silicone buttons; The sampler is equipped with a shell, which is easy to install and provides insulation protection; The shunt is made of pure copper material, which has good conductivity and will not consume too much battery power in standby mode;<br><br>It can automatically identifycharging and discharging, the charging capacity increases, the discharging capacity decreases, remaining capacity is displayed in real time; It supports setting two different screen brightnesses during the day and night, and can freely switch between three off-screen modes. Overvoltage, undervoltage, overcurrent, overpower, external overheating, low temperature protection can be set. When the protection condition is reached, there will be an alarm sound and a -up window reminder, and the relay will disconnect the circuit (the delivery list does not include the relay); Provide mobile APP, support Android and mobile phones to view data through Bluetooth, view charge and discharge curves, and support historical data export; Provide communication protocol, use 485 communication to control the instrument; Voltage measurement range: 0-120V Voltage resolution: 0.01V Temperature measurement range: -20-120 Ampere-hour measurement range: 0~9999.99AH Watt-hour measurement range: 0~9999.99kWH Bluetooth communication distance: Up to 10 meters (No obstacle) Voltage accuracy: 1%+2 digits Sampling rate: 1 time/second Colour:As Shown Material:plastic+metal Current measurement range: 0~100A type:KH110F<br><br>Package Contents: 1 x Coulomb Counter Kit<br><br>Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
