Drying is continued until the piece is completely dry (when no further weight loss occurs) and this oven dry weight recorded. The moisture content of a powder is the loss in weight (%) after oven drying at 102°C until constant weight is obtained. The weight loss is calculated as moisture. Nondestructive quality assessment of chili peppers using near-infrared hyperspectral imaging combined with multivariate analysis. The oven-dry test works well for obtaining the moisture content of a sample, but it can also be used to obtain information about the moisture distribution within a piece of wood. This is a laboratory test because we need an oven for this test to perform and certainly we cannot carry an oven into the field. The moisture content of a soil is frequently used throughout geotechnical engineering practice both in the laboratory and in the field. Let us know in the comments what you think about the concepts in this article! You’ve supercharged your research process with ACS and Mendeley! of water content by Karl Fischer method.
