Product Description
General rechargeable battery internal resistance tester Abbreviation: battery internal resistance tester.It is a measuring instrument used to measure the internal resistance, voltage and temperature of rechargeable batteries such as lead storage batteries and lithium batteries to determine the health of the battery. It can also be used as a meter to measure the ESR parameters of electrolytic capacitors (for reference only).This meter 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 wire, terminal and battery electrode.It also has functions such as data storage, data access, alarm, and automatic shutdown.The whole machine is high-grade and beautiful, with wide measuring range, high resolution, convenient operation, easy to carry, accurate, reliable, stable performance, and strong anti-interference ability. It is an indispensable instrument for battery production, battery installation, equipment production, equipment maintenance and other scenarios.
General rechargeable battery internal resistance tester controlled by a microprocessor, the internal 16-bit ADC can accurately detect battery internal resistance, voltage and temperature. It is characterized by measuring without stopping the UPS system, using AC low-resistance measurement and noise reduction technology, without stopping the normal operation of the device under test, and measuring under the running state, which greatly shortens the test time.At the same time, it has the functions of data storage, histogram display, data upload, computer, mobile phone, tablet and other smart devices Bluetooth connection for wireless measurement and data access.
