LR8431 – Memory HiLogger

Overview

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
