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. Data can be downloaded using Hioki’s tablet and smartphone app (for Android devices). Search for “HIOKI” and download the Wireless Logger Collector!
A compact 1-channel wireless logger that can predict the ease with which fungus grows
Temperature, Humidity, Fungal index, Growth prediction
Fungal index – Calculated based on temperature and relative humidity – This index predicts how easy it is for fungi to grow. The fungal index is indicated by a value from 0 to 200, and can be used to predict the period of time until the start of fungal growth and contamination.
Growth Prediction – Calculated based on the fungal index – Since fungal growth occurs when the necessary environmental conditions are maintained over a certain period of time, the cumulative value estimated from the fungal index can be used to predict fungal contamination. The Hioki LR8520 uses illustrations to indicate fungal growth in 5 stages based on the accumulative value. Easily Predict Fungal Growth Based on 2 Indices
Application: Food and Grain Storage
Issue Grain is traded in terms of weight, but its quality is maintained by keeping the grain as dry, and therefore as light, as possible. On the other hand, increased humidity brings about the risk of fungal contamination. If fungal contamination is discovered, the entire volume of product must be destroyed.
<< Resolved with WIRELESS FUNGAL LOGGER >>
You can easily check if environmental conditions promote fungal growth in order estimate how high the humidity can be safely raised.
Application: Buildings
Issue Since buildings have a high degree of air tightness, fungal growth occurs easily in any season. In the summer, fungal growth occurs easily in areas subject to cool air from air conditioning units. Air conditioning is set to excessively control temperature and humidity in an attempt to prevent fungal growth.
<< Resolved with WIRELESS FUNGAL LOGGER >>
Easily identify the range in which fungal growth occurs in order to moderate air conditioner settings and conserve energy.
A wireless logger whose data can be captured by a smartphone or PC
Built-in Bluetooth(R) wireless technology. Use your tablet or PC to collect data even as signals are being logged. No matter what time during measurement you collect the data, data is automatically merged together into one single file. Review data trends by observing waveforms and numerical values right there in the field. *Pictured: LR8514
Real-time monitoring
By using the Hioki LR8410-20 to acquire data, you can view the waveforms in real time. Furthermore, previous waveforms can be viewed while the device is taking measurements. *Pictured: LR8514
A compact wireless logger that you can place anywhere
Pocket size for installation anywhere. Resolves issues involving installation space. Wireless capability is useful when you need to collect data from high places or locations scattered across a large site.
Power with AA batteries or an AC adapter
The logger will operate for about 20 days on two AA-size alkaline batteries. (Recording interval: 1 sec, with Bluetooth(R) ON) Since the batteries will last longer the less time the Bluetooth(R) function is operating, the instrument features a power-saving function that automatically turns on the Bluetooth(R) circuit during predefined time periods. While communications are disabled, data is reliably stored in the instrument’s large built-in memory, which can hold 500,000 data points per channel. Use the AC adapter to record data over extended periods of time with peace of mind.
A temperature and humidity logger that can generate alarms
Using the built-in alarm function, if measured signals fall outside defined ranges,”ALARM” can be displayed. You can also connect the logger to an external buzzer or warning indicator lamp. (The buzzer and warning indicator lamp must be prepared separately.) You can also use the LR8520 as a 1-channel temperature and humidity logger that can generate alarms.
*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.
