Product Description

Battery Interconnection Resistance Tester Determines Health of Head-acid Cells

General Information:
EPFS520 Battery Impedance Tester (also called Battery Internal Resistance Tester) is a measuring instrument used to measure the internal resistance, voltage and temperature of rechargeable batteries such as lead batteries and lithium batteries to determine the health of the battery. This instrument uses the AC 4-terminal test method to measure the internal resistance of the battery, which 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, and equipment maintenance.

EPFS-2P Battery Impedance Tester is controlled by a 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 equipment 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, and data upload to the computer.
