GB/T 29249-2012
Electronic weighing moisture analyzer of oven drying

This standard serves as the national recommended technical specification for electronic weighing-based moisture analyzers using the drying method. It defines the terminology, technical requirements, test methods, and inspection rules for such instruments, and applies to the determination of free moisture in samples that are relatively stable in physical and chemical forms. The instruments covered by this standard operate on the principle of weight loss upon drying, integrating a high-precision electronic weighing system with a heating device (such as a halogen lamp, infrared heater, etc.) to automatically calculate moisture content by measuring the mass difference of the sample before and after heating. Such instruments are widely used in various industries, including grain, food, and chemical sectors.
