Adopting GB/t11013-1996 and IEC61436: 1998 testing methods, which is accurate and reliable;
Testing the battery AC internal resistance and open circuit voltage quickly and directly;
Simple circuit, highly integrated and strong anti-interference ability. The constant AC current is less than 20mA, and the performance is stable and reliable;
Advanced digital display tube, data display stably and easy to read;
Customized testing wire can reduce error;
The voltage and internal resistance are displayed by a 3-and-a-half digit meter, which can automatically switch the internal resistance range without shifting, and the operation is convenient;
The cell and module internal resistance and voltage is testing and display at the same time;
Widely testing range, suitable for testing various types of cells and modules with voltage≤20V and internal resistance≥10mΩ;
Beautiful appearance, firm structure, small volume and easy to carry.
