Description
Data Logger LR8101 LR8102 for High-Precision Modular Testing
The Data Logger LR8102 is a versatile modular system engineered to meet the demanding requirements of modern embedded and high-voltage applications. As electric vehicle technology and energy-efficient devices advance, measurement systems must provide high accuracy, safety, and multi-channel capability. Hioki’s LR8101 (standard) and LR8102 (advanced) deliver these capabilities with a modular approach, allowing users to configure and expand their measurement systems according to project needs.
With the LR8102, multiple data loggers can be synchronized to increase the number of channels while maintaining precise, simultaneous sampling. High-speed data output via UDP ensures real-time monitoring, essential for HIL simulations or rapid analysis during battery and inverter testing. The LR8102’s advanced architecture supports up to 3,000 voltage and temperature channels and 120 channels for power measurement, making it ideal for high-voltage battery packs, PV inverter production, and complex power electronics testing.
Safety is paramount when working with high-voltage systems. The LR8102, combined with modules like the Power Measurement Module M7103 and Voltage/Temperature Modules M7100 or M7102, provides high terminal-to-ground and module-to-module voltage ratings, enabling secure measurement of battery cells and inverter outputs. This ensures accurate capture of voltage, current, and temperature profiles during charge/discharge cycles or production line testing.
Hioki’s data loggers also provide easy integration with external systems via CAN, SD card, or USB storage. Users can precisely track battery cell performance, energy conversion efficiency, and PV inverter behavior in compact, scalable configurations. With modularity, safety, and real-time capabilities, the LR8102 turns complex measurement challenges into actionable insights.
