WIRELESS UNIVERSAL UNIT LR8531

Key Features

15 channels. Voltage, temperature (thermocouples, Pt100/1000, JPt100), humidity, and resistance measurement
Wireless connection between LR8450-01 and measurement module, 30 m range
Sampling rate of up to 10 ms with 15 channels
For DC voltage measurement and temperature measurement using a RTD can be performed.

• LR8531 cannot perform measurement by itself. Memory HiLogger LR8450-01 is required separately.
• By attaching the Z3230 Wireless LAN Adapter (accessory), LR8531 can be wirelessly connected to the Memory HiLogger LR8450-01.
• The LR8450-01 and wireless modules emit radio waves. Use of radio waves is subject to licensing requirements in certain countries. Using them in a country or region other than those indicated may violate the law and may result in legal penalties.
• For the latest information about countries and regions where wireless operation is currently supported, see the "Specifications."
