Icon Nr. 14) Group I: (Emissivity = 0,93): Materials such as concrete (dry), brick, sandstone, mortar, marble, stucco, Group II (Emissivity = 0,85): granite, cobblestone, fibreboard, wallpaper, varnish...
Page 3 Group III (Emissivity = 0,75): porcelain (white), varnish (bright), cork, cotton 3. Area of measurement The laser circle indicates the area of measurement. Optimal working distance is 1 m – measurement can be done from 0,1 m to 5 m 4.
Page 4 Green = No mould conditions; Technical background: Surface temperature is higher than dew point temperature Yellow = Deviation to optimal conditions Red = Surface temperature corresponds with dew point temperature  If a there are mould conditions red LED turns on indicating that there is a risk.
