XIAMENUniversal Rechargeable Battery Internal Resistance Tester
SPECIFICATIONS
The TOB-ES8020 Universal Rechargeable Battery Internal Resistance Tester is a measuring instrument used to measure the internal resistance, voltage and temperature of rechargeable batteries such as lead storage batteries, lithium batteries and other rechargeable batteries, in order to determine the health status of the battery, and also as a meter to measure the ESR parameters of electrolytic capacitors (for reference only).
This instrument uses the AC 4-terminal test method to measure the internal resistance of the battery, and the correct measurement value can be measured without being affected by the contact resistance between the test wire, terminals and battery electrodes. Meanwhile, it also has the functions of data storage, data review, alarm and automatic shutdown.
The whole machine is high-grade and beautiful, wide range, high resolution, convenient operation, easy to carry, accurate, reliable, stable performance, anti-interference ability strong. It is an indispensable instrument for battery production, battery installation, equipment production and equipment maintenance.
The universal rechargeable battery internal resistance tester is controlled by microprocessor, internal 16-bit ADC can accurately detect the internal resistance, voltage and temperature of the battery. It is characterized by measuring without stopping the UPS system, using AC low-resistance measurement and noise reduction technology, without stopping the normal work of the equipment under test, and measuring in the running state, which greatly shortens the testing time. At the same time with data storage, histogram display, data upload computer, cell phone tablet and other smart devices Bluetooth connection for wireless measurement, access to data and other functions.
