Determination of Surface Moisture Content of Wood Utilizing a Colorimetric Technique
Keywords:Cobalt chloride (CoCl<sub>2</sub>) hydrate, colorimetric technique, surface moisture content, CIE L<sup>*</sup>a<sup>*</sup>b<sup>*</sup>, spectrophotometer
AbstractOptical properties of cobalt chloride (CoCl2) hydrate, whose color changes with surrounding humidity, were used to develop a colorimetric technique for determining surface moisture content of wood nondestructively. The colorimetric CoCl2 treated wood technique for determining surface moisture content through color degree change in CIE L*a*b* color space has been experimentally verified.
