LDNZ battery internal resistance tester is a portable and multifunctional battery testing instrument. This tester is designed for quickly and accurately measuring key parameters such as internal resistance, voltage, and conductivity of batteries. It is widely used in fields such as communication, power, railway, transportation, finance, and data centers, and is an important tool for battery maintenance and management. Adopting advanced AC discharge method, combined with high-performance microprocessor and color touch screen technology, it provides users with intuitive and easy-to-use operation interface and accurate and reliable measurement results.

High precision measurement: Using high-precision measurement circuits, the internal resistance measurement accuracy reaches ± 0.5%, and the voltage measurement accuracy reaches ± 0.2%, which can accurately reflect the health status of the battery.

Multi functional integration: This tester not only has internal resistance measurement function, but also can simultaneously measure the voltage and conductivity of the battery, providing comprehensive battery performance evaluation. In addition, it also supports online testing of individual batteries and battery packs to meet testing needs in different scenarios.

Intelligent recognition and automatic measurement: The tester has automatic recognition functions for forward and reverse connections, without the need to manually switch the polarity of the test clamp, making operation more convenient. At the same time, it supports one click start of automatic measurement, allowing users to quickly obtain test results by simply setting test parameters.

Large capacity data storage and management: Built in large capacity lithium battery and 8GB TF card, supporting long-term testing and large-scale data storage. Users can export test data to a computer through a USB interface and use the accompanying upper computer software for in-depth data analysis and report generation.

Handheld portable design: Adopting a handheld design, weighing no more than 0.5Kg, it can be easily operated with one hand. Equipped with high-performance lithium batteries, supporting long-term standby and continuous testing, suitable for outdoor and on-site use.

Intuitive and easy-to-use operation interface: adopting a 5-inch true color touch screen with a resolution of up to 800 * 480, the interface is clear and intuitive, and the operation is simple and fast. Supports dual operation modes of resistive touch and buttons to meet the usage habits of different users.

Multiple safety protection: It has multiple safety protection functions such as overvoltage, overcurrent, and short circuit to ensure the safety and reliability of the testing process. At the same time, high-performance lithium batteries and intelligent charging management systems are used to effectively extend the battery's lifespan.
