Fungal Growth Rate at a Glance! Prevent Fungal Occurrence in Business Critical Locations

SKU: WIRELESS FUNGAL LOGGER LR8520 Categories: , , ,


Hioki Memory HiLoggers are high-speed data loggers for recording multiple channels of voltage, temperature, resistance or humidity signals, some models providing complete isolation between channels and strong noise resistance. The Hioki LR8520 is a wireless and compact 1ch logger that records fungal index and growth prediction to easily prevent fungal growth. The logger utilizes Bluetooth® technology to either send measured data to the Hioki LR8410 Wireless Logging Station or to an Android (TM) tablet. WIRELESS FUNGAL LOGGER LR8520

LR8520 main unit only, humidity sensor is sold separately

*1 Fungal index was proposed by Keiko Abe, Doctor of Agriculture and Director of the Institute of Environmental Biology (Japanese Patent Number 2710903). The LR8520 alone is not capable of making measurements – please also purchase applicable sensor. Only the temperature and humidity sensors affect the measurement accuracy and are subject to calibration. The LR8520 logger does not require calibration. *Bluetooth® is a trademark of Bluetooth SIG, Inc. and licensed for use by HIOKI E.E. CORPORATION.


Key Features

• High-precision ±3% rh humidity sensors
