T-315 battery tester

battery tester

The T-315 battery tester is a measuring instrument used to measure the internal resistance, voltage and temperature of rechargeable batteries such as lead-acid battery and lithium battery, so as to judge the battery health status. At the same time, it can be used as an instrument to measure the ESR parameters of electrolytic capacitor (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.

 

The T-315 battery tester is controlled by microprocessor, and the internal 16 bit ADC can accurately detect the 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 tested equipment, and measuring under the running state, which greatly shortens the test time. At the same time, it has the functions of histogram display, data upload to computer, PDA and other intelligent devices, such as Bluetooth connection for wireless measurement, data access and so on.
