Device for detecting fungal contamination of surfaces, useful for determining air quality in buildings, comprises culture medium close to the surface, fitted with optical sensors

摘要

A device for detecting contamination of a surface by fungi comprising, a growth substrate (A) placed on or near the surface, which contains: (a) a nutrient medium that provides better growth conditions for fungi than the test surface; and (b) at least one optical sensor unit that is positioned so that is can read the optical properties of the medium, is new. An Independent claim is also included for detecting fungal contamination of a surface comprising: (i) placing (A) on or near the surface; (ii) detecting optical scattering properties of (A); (iii) comparing the measured properties with reference data; and (iv) generating a signal if the comparison reaches a predetermined decision value.
