IR TESTER & VOLTAGE CHECKING MACHINE

Product Data Sheet

Fast & Accurate Internal Resistance and Voltage Measurement for Battery Quality Control

The IR Tester & Voltage Checking Machine is a versatile and high-precision diagnostic tool engineered for the rapid testing of internal resistance (IR) and voltage (OCV) in lithium-ion batteries, battery packs, and modules. Designed for integration into battery manufacturing lines, quality control labs, and R&D environments, this compact and efficient machine ensures accurate and repeatable results for various cylindrical and prismatic cells.

Whether you're conducting incoming quality inspection (IQC), cell sorting, or battery grading, this machine is a critical component for any workflow requiring precise IR and voltage data — helping you detect faults, match cells, and ensure pack uniformity for optimal performance and safety.

Key Features

  • High-Precision Testing
    Accurately measures internal resistance (in milliohms) and open-circuit voltage (OCV) with high-speed microprocessor control and Kelvin 4-wire technology.

  • Ultra-Fast Measurement
    Test time of less than 20 milliseconds per cell, making it suitable for high-throughput production lines and real-time sorting machines.

  • Wide Measurement Range
    Supports voltage testing up to 20V and internal resistance from 0.1mΩ to 200mΩ, ideal for single cells and battery packs.

  • Real-Time Digital Display
    Bright and intuitive LED display shows voltage and resistance values simultaneously for instant decision-making and troubleshooting.

  • Automation-Ready
    Integrates easily into automated cell sorting systems or QC stations using RS232 or USB interface.

  • Compatible with All Cell Types
    Suitable for 18650, 21700, 32700, prismatic cells, and custom battery packs — a universal solution for all battery testing needs.

  • Auto Zeroing & Calibration
    Built-in self-calibration maintains testing accuracy over time without the need for manual adjustments.

  • Compact & Portable
    Lightweight and space-saving design fits into any testing station, from manual inspection desks to automated conveyors.
