HT3561-12H/24H Multi-channel Battery Tester

The HT3561-12H/24H multi-channel battery tester can quickly complete the internal resistance and voltage sorting test of the maximum 24-channel battery. Based on the identical test circuit of the classic HT3561, the test speed and accuracy of this device are in leading position of the industry. They are the ideal supporting tool for automated test manufacturers.

Hope Instrument also provides external multi-channel scanning card for multi-channel battery sorting or multiple battery packs. The wiring shows as following:



HT3561 series instrument comes standard with RS232/RS485 and I/O interface, especially suitable for supporting automatic equipment to complete automatic test.

Integrated the multi-channel scanning card inside the instrument, HT3561 has the advantages of fast scanning speed, strong anti-interference ability and long switch life. It is more convenient to use and more powerful.

The HT3561-12 and HT3561-24 multi-channel resistance tester can be used for both single-channel test and multi-channel test; They support single-card 12-channel in four-terminal test and max of 24-channel test.
