- AN-200WB can easily measure the moisture and protein content of wheat, barley and soybeans. For soybeans, it can also measure oil content. As the analyzer utilizes the nearinfrared penetration method, sample preparation, such as crushing, etc before measurement is not required. Simply by placing the sample in the sample case and inserting this into the measuring chamber, the sample is measured automatically. An automatic elevating mechanism moves the sample case, measuring different parts of the sample and an average value is displayed after about 20 s.
