- The AN-900 is capable of measuring moisture content, Protein and Amylose in Short & Long Brown Rice and Milled Rice. Constituents are calculated based on the transmittance of the light. Processing of samples, such as husking and grinding etc., are not necessary with the AN-900. Measurements are started by simply loading a sample into the sample case. This allows quick, simple and non-destructive constituent analysis. Compared to the infrared reflectivity measurement method, the Near-Infrared Transmittance method employed by the AN-900 is relatively little affected by the shape or color of the sample and thus excellent measurement characteristics.
