HIOKI MEMORY HiLOGGER LR8431

MEMORY HiLOGGER

LR8431

Portable Handheld 10-channel Data Logger with 10ms Simultaneous Sampling

Hioki Memory HiLoggers are high-speed data loggers for recording multiple chanels of voltage, temperature, pulse or rotation signals, providing complete isolation between channels and strong noise resistance . The LR8431 logs data at 10ms speeds across 10 channels simultaneously, and features a bright color LCD for crystal clear waveform displays.

Key Features

• Record measurement data on a USB flash drive for easy transfer to a computer • Record to reliable Compact Flash cards during long-term measurement applications for increased peace of mind • Replace storage media during real-time recording • Improved thermocouple measurement accuracy and reference junction compensation accuracy • Ten isolated analog input channels • 10 ms sampling and recording across all channels • Noise-resistant measurement circuitry for improved readings • Ultra-compact for convenient portability • Widescreen, bright LCD gives excellent viewability

■ Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)
