Data Logger to Prevent Fungal Occurrence in Business Critical Locations
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.
<Supported measurement parameter>
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
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.
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.
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
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.

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.
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.
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.
