Battery Internal Resistance Tester-BK-300

BK-300 battery internal resistance tester is a new – type instrument for testing battery internal resistance using alternating current. It can also test the battery voltage simultaneously. It has the characteristics of simple operation, practicality, reliability, and high performance – price ratio. The test adopts a four – wire fixture, effectively eliminating measurement errors caused by lead resistance. The tester can set battery internal resistance non – conformity alarm values according to user requirements. It is mainly used for sample production in battery material research and development, and is an ideal equipment for your production and assembly of batteries.
