Internal Resistance Tester

It is designed for internal resistance test of common rechargeable cell and battery pack.
According to international standards, it adopts AC 1000Hz±10% alternating current method to test AC internal resistance of battery or cell.
We initiate 50 mΩ standard resistance built-in the tester, which makes the calibration convenient and fast.
We provide a measurement and control software, which can connect with computer to record test data.
