Sine Wave Battery Internal Resistance Detector Monitor The Battery Temperature Battery Tester ,Easy to Operate

This instrument is a precision instrument that uses 1kHz sine wave to measure the internal resistance of the battery and uses an infrared probe to monitor the battery temperature, which can effectively evaluate the use status of the battery. Measure the internal resistance of the battery offline and measure the battery voltage at the same time.

The internal resistance is measured by a 1KHz constant current source, and the "four needles and four wires" method is used to eliminate the influence of lead wire resistance and contact resistance, making the measured value more accurate High-resolution battery internal resistance measurement uses a 0.01m 1KHz sine wave constant current circuit to measure battery voltage With data comparison function, it can be used for fast battery screening with relative measurement function Can be used to remove lead resistance, large backlit LCD display, sub-display area automatically indicates low voltage and has the letter "Lob", rechargeable ternary lithium battery
