Description
Overview
GAOTek Portable Other Electrical Tester Tools are used to measure the internal resistances, voltages, and temperatures of rechargeable batteries such as lead-acid batteries and lithium batteries, to judge the battery health statuses. At the same time, they can be used as instruments to measure the ESR parameters of electrolytic capacitors (for reference only). The instruments use the AC 4-terminal test method to measure the internal resistances of the batteries and can measure the correct measurement values without being affected by the contact resistances between the test lines, terminals, and battery electrodes. At the same time, they also have the functions of data storage, data access, alarms, automatic shutdown, and so on. All machines have the advantages of high-grade and beautiful appearances, wide ranges, high resolutions, convenient operations, convenient carrying, accuracy, reliability, stable performances, and strong anti-interference abilities. They are indispensable instruments for battery production, battery installation, equipment production, equipment maintenance, and other scenes. These portable battery testers support the maintenance of UPS and storage batteries critical to the life support of all businesses. These battery internal resistance testers set the standard for assessing the deteriorations and remaining lives of UPS and other lead-acid batteries by giving complete diagnoses via battery resistance testing.
