Våttnemåling
Våttnemåling is a term used in Norwegian to describe methods for determining the moisture content of a material or environment. It covers measurements of water content in soils, wood, concrete, foodstuffs and other porous materials, and is important for assessing stability, processing efficiency, and quality control.
Moisture content can be expressed as gravimetric moisture content (the ratio of the mass of water to
Common methods include gravimetric (loss-on-drying by oven at 105–110 C), which is a reference method; dielectric
Applications span agriculture for irrigation planning; construction and concrete drying and quality control; forestry for drying
Standards and accuracy: ISO, ASTM and regional standards exist for specific materials and methods. Results can
