Battery internal resistance tester

  Product decscription  Currently, VRLA battery internal resistance test has been widely used in the daily maintenance of the battery voltage check and replaced the traditional  method. Because the internal resistance of the battery is the main parameters of the battery .Internal resistance has been recognized  as an accurate and quick way to determine the health of the of the battery.  Feature:
High precision online testing, Full automatically switch the testing range,Great capacity data storage. 1. Automatically switch the testing range between 0.000mΩ-99.999mΩ. 2. It can store 999 groups battery parameter.(Max. 500 cellbattery per group) 3. It can store 200 groups battery parameter setting. English Menu, 320*240 LCD Display.  Connect to PC by USB or RS232 and transmit the testing data to PC and storage, it is convenient to analysis the battery according to the history data. Powerful data management function.  Enhanced over pressure protecting function. Self recovery the over current protecting function. Use the SOC chip to improve the tester stability. Big capacity Lithium cell and AC 100V-240V power supply Low battery indicate. Smart and portable. Automatic testing mode make user to test expediently. Powerful PC software for manage the testing data. 1. Automatically analysis batrtery badstate. 2. Building the history record base, describe the battery sate curve. 3. Batteries are contrastived analysis in the same battery pack.  4. All batteries are administrated by different levels(excellent, good, medium, bad) Function 1. Test the battery voltage and internal resistance online. 2. Battery internal resistance and voltage out of gauge alarm. 3. All the battery parameter are marked group No.to make the user manage the data expediently. 4. PC software can analysis the battery according to the history data. Technical indicator:
