Improved Instrument to Measure the Moisture Content of Lint Cotton, Seed Cotton, and Cottonseed

The cotton and cottonseed industries are modernizing technical methods and instru ments along with suppliers of other raw materials. Described herein is an improved electrical conductivity instrument for measuring rapidly and accurately the moisture content of lint cotton, seed cotton, and cottonseed. Moisture contents in percentages, based on total weights of samples, are indicated on a direct reading dial. Accurate measurements of ± 1% in the 3.3-22% moisture range are obtainable with this instru ment when compared with standard oven metheds. A relatively large representative sample (35 g. lint cotton, 100 g. seed cotton and cottonseed), control of sample density (600 lb./sq. in. pressure), and a stable electrical system are the contributing factors for a successful instrument.
