The HIOKI LR8431-20 Memory HiLogger records voltage, thermocouple temperature and pulse signals for equipment evaluation and troubleshooting. Its ten analog inputs are isolated, while the four pulse inputs share a common ground.
Configuration: Thermocouples are supplied separately. The 9780 battery, 9782 case and 9728 card are included in the PRO Kit only.
See Accessories Included for the exact quantities supplied with this configuration.
Contact RCC Electronics for configuration assistance and Canadian application support.
Instrument specifications apply under HIOKI's stated measurement conditions. Kit contents are listed separately.
