The Moisture Analyzer determines the moisture content of a sample by measuring the loss in mass during controlled heating. A precision balance continuously records the sample weight while a halogen or infrared heating unit removes moisture. The instrument automatically calculates moisture percentage, dry matter content, and weight loss with high accuracy and repeatability. This method provides much faster results than conventional oven drying and is widely accepted for routine laboratory and industrial quality control.
