Hioki Memory HiLogger LR8431

Model No :

Hioki LR8431

Part Code :

LR8431-20

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.

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

Major Applications

- Evaluating motors and inverters used in electric and hybrid vehicles
The LR8431-20 enables stable, low-noise measurement of high-speed, high-resistance targets
- Efficiency measurement and performance evaluation of air conditioning equipment
