The HIOKI LR8531 wireless universal unit extends an LR8450-01 logger with 15 measurement channels. It communicates through the supplied wireless LAN adapter and cannot operate as a standalone logger.
Configuration: An LR8450-01 logger and suitable sensors or input wiring are required separately. Z3231 is a standard module accessory and is counted only once in the kit total.
See Accessories Included for the exact quantities supplied with this configuration.
Contact RCC Electronics for configuration assistance and Canadian application support.
