Description
Memory HiLogger LR8431 for High-Speed Multi-Channel Measurement
The Memory HiLogger LR8431 is a versatile and portable data logger built for engineers who need fast, accurate, and dependable multi-channel measurements. Designed to handle voltage, temperature, pulse, and rotation signals, this 10-channel logger delivers simultaneous 10 ms sampling across all inputs, making it ideal for capturing rapid changes in dynamic systems.
One of the standout advantages of the Memory HiLogger LR8431 is its complete isolation between all ten analog channels. This design eliminates interchannel interference and enhances operator safety, even when measuring temperature and voltage at the same time across components with different electrical potentials. The result is clean, stable data acquisition in demanding environments such as electric vehicle development, inverter testing, and electronic equipment evaluation.
The LR8431 offers exceptional flexibility in data storage. Measurement data can be recorded directly to a USB flash drive for quick transfer to a computer or saved to Compact Flash cards for long-term, high-reliability recording. Storage media can even be replaced during real-time measurement, allowing uninterrupted data collection during extended tests.
Despite its powerful capabilities, the Memory HiLogger LR8431 remains extremely portable. Its palm-sized design and bright color LCD make it easy to deploy on production floors, in laboratories, or in the field. The built-in display provides excellent waveform visibility, enabling engineers to verify signals instantly without relying on external devices.
For deeper analysis, the included Logger Utility software allows users to record data directly to a PC, review historical data during active measurement, and perform post-test analysis through a USB connection. Whether evaluating motor performance, measuring thermal behavior in electronic assemblies, or tracking rotational speed via pulse inputs, the Memory HiLogger LR8431 delivers precision, reliability, and convenience in a single compact instrument.
