Fungal Index

1.2 Fungal Index

A fungal index is an indicator to help predict how fungi are likely to grow. Fungal growth correlates with temperature and relative humidity and a fungal index can be calculated from temperature and relative humidity. It is mainly used to quantitatively indicate the climate of fungal growth indoors as a numerical value (Japanese Patent Number 2710903). The instrument calculates a fungal index between 0 and 200 from temperature and humidity using a highly accurate temperature and humidity sensor.

Fungal contamination starts even more quickly in an environment where the contamination is already progressing or fungi are fed and nourished.

Predicted fungal growth
Fungal growth is predicted at 5 levels (measurement value: 0 to 4) from the accumulated fungal index. The following symbols appear in the display of the instrument.

(No symbol)

No new spores are growing.
Measurement value: 0

A hypha starts extending.
Measurement value: 1

New spores are growing.
Measurement value: 2

Spores start spreading.
Measurement value: 3

A lot of spores are spreading (the spore part in the display blink).
Measurement value: 4

A fungal index is a highly reliable indicator based on academic research, however, it does not guarantee that fungal growth is completely controlled in any environment with a low fungal index.
