Description
Overview
The GAOTek Portable Battery Tester with Internal Resistance and Voltage Measurement is a measuring instrument used to measure the internal resistance, voltage, and temperature of rechargeable batteries such as lead-acid and lithium, to judge the battery health status. At the same time, it can be used as an instrument to measure the ESR parameters of electrolytic capacitors (for reference only). The instrument uses the AC 4-terminal test method to measure the internal resistance of the battery and can measure the correct measurement value without being affected by the contact resistance between the test line, terminal, and battery electrode. At the same time, it also has the functions of data storage, data access, alarm, automatic shutdown, and so on. The whole machine has the advantages of high-grade and beautiful appearance, wide range, high resolution, convenient operation, convenient carrying, accuracy, reliability, stable performance, and strong anti-interference ability. It is an indispensable instrument for battery production, battery installation, equipment production, equipment maintenance, and other scenes. T-315 portable battery testers support the maintenance of UPS and storage batteries critical to the life support of all businesses. This battery internal resistance tester sets the standard for assessing the deterioration and remaining life of UPS and other lead-acid batteries by giving a complete diagnosis via battery resistance testing.
