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. Differential Method for Precision Colorimetric Analysis. For example, samples can be cut every foot along the length of a board to determine how moisture content changes or a piece of wood can be sliced to determine the moisture profile through the thickness. It is the simplest and the most commonly adopted method for the determination of water content. Communication Through Soil in Wireless Underground Sensor Networks – Theory and Practice. Moisture content is derived from the loss of product weight during drying by measuring the change in mass of a sample while being heated at a controlled rate until no more change in weight is observed.

Successful approaches for a variety of food products were summarized and their findings discussed. It is found that water content of soil sample obtained by Pycnometer method is the highest that is 24.00 % amongst the three methods , Second highest is obtained by Oven- drying method and is 20.74% and least water content is obtained by Rapid Moisture Meter as 12.37%. Moisture content determination of soils using Oven Drying Method ASTM D2216 needs considerable time which may not be feasible on occasions where more rapid results are required. The weight loss is calculated as moisture. 1954 Report and Recommendations of Committee on Balances and Weights. This weight loss will be then used to calculate the percentage of water content w in the soil. The difference in the two weights (Loss on Drying) is then compared with either the original weight (Wet-base test) or final weight (Dry-base test) and the moisture content calculated. Preservation of Bacteria by Lyophilization. Metal container Balance (0.01 g accuracy) Procedure The number of the container is recorded, cleaned, dried and weighed.
