Sm8126A Battery Internal Resistance Tester with 1 kHz Sine Wave Constant Current Circuit

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 battery's use status.

Features:

High resolution battery internal resistance measurement 0.01 mΩ

Adopt 1 KHz sine wave constant current circuit

Can measure battery voltage, optional infrared temperature probe,Measuring battery heating

Kelvin four-wire test clamp

With data comparison function, it can be used for rapid battery screening

With relative measurement function, it can be used to remove lead resistance

Large screen backlit LCD display

The sub-display area automatically prompts low voltage with "Lob" letters
