Battery Internal Resistance Tester Lead Battery Measurement 200ms Response Time

Product Overview

Universal Rechargeable Battery Internal Resistance Tester Abbreviation: Battery Internal Resistance Tester, is used to measure the internal resistance, voltage and temperature of lead batteries, lithium batteries and other rechargeable batteries, in order to determine the state of health of the battery measurement instrument, and at the same time, it can be used as a measurement of electrolytic capacitance ESR parameters of the instrument (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, terminal and battery electrode. At the same time also has data storage, data access, alarm, automatic shutdown and other functions. The whole machine is high-grade and beautiful, wide range, high resolution, convenient operation, easy to carry, accurate, reliable, stable performance, strong anti-interference ability. It is an indispensable instrument for battery production, battery installation, equipment production, equipment maintenance and other scenes.

Universal rechargeable battery internal resistance tester is controlled by microprocessor, internal 16-bit ADC can accurately detect battery internal resistance, voltage and temperature. Its characteristics are measured 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 measured in the running state, which greatly shortens the test time. At the same time with data storage, histogram display, data upload computer, mobile phone tablet and other smart devices Bluetooth connection for wireless measurement, access to data and other functions.
