The Hioki LR8450 Memory HiLogger delivers high-speed multi-channel data acquisition, extreme electrical isolation, and modular parameter versatility engineered specifically for electric vehicle (EV) battery validation, automotive testing, renewable power systems, and industrial plant process logging.

Advanced Multi-Channel Data Logging with the Hioki LR8450 Memory HiLogger

Designed to bridge the gap between continuous data logging and dynamic waveform capture, the Hioki LR8450 Memory HiLogger provides simultaneous sampling across extensive electrical and physical sensor inputs. Capable of mounting up to four modular plug-in input units directly on its chassis, the base instrument handles up to 120 isolated wired analog channels without requiring auxiliary external expansion racks. Its core high-speed acquisition engine reaches sampling intervals down to 1 ms, enabling test engineers to capture transient voltage surges, fast thermal changes, and mechanical strain spikes simultaneously.

The instrument provides exceptional high-voltage safety ratings. Equipped with robust channel-to-channel galvanic isolation rated up to 1000 V AC/DC, the data logger prevents electrical ground loops and equipment breakdown when measuring multiple series-connected battery cells in high-voltage energy storage systems (BESS) and EV powertrain platforms. Real-time test trends are rendered across an integrated 7-inch high-visibility color TFT LCD screen, allowing operators to monitor live waveforms, zoom into historical events, and configure multi-level trigger alarms on the shop floor.

For automated data aggregation, the logger incorporates a Gigabit Ethernet interface and USB 2.0 ports. Test results and audit trails stream in real time to network servers via FTP or save locally onto standard SD cards and USB memory drives in tamper-resistant binary and universal CSV formats for seamless spreadsheet analysis.

Frequently Asked Questions

Can the Hioki LR8450 Memory HiLogger mix different measurement modules simultaneously?
Yes. The Hioki LR8450 Memory HiLogger supports any combination of plug-in modules across its four physical slots. You can combine high-speed voltage units, universal thermocouple/RTD units, and strain gauge measurement units within the same test setup to sample multiple physical parameters at their respective required sampling rates.

How is continuous long-term data logging recorded without memory overflow?
The instrument streams data in real time directly onto high-capacity SD cards or USB flash drives. It features segment-based circular logging and auto-file-saving capabilities, enabling months of continuous unattended recording without running out of memory.

Can the data logger be operated and monitored remotely?
Yes. Using its integrated Gigabit Ethernet port and built-in HTTP server, technicians can access the device from any web browser to view live waveforms, check current readings, and download historical data files without installing dedicated client software.
