CropScan 1000B is a Near Infrared Transmission Analyser designed to measure protein, oil, starch and moisture in whole grains of wheat, barley, oats, sorghum, canola., corn and soybeans. An optional test weight module is available for the CropScan 1000B. The CropScan 1000B uses a diode array spectrometer to scan the wavelength region, 720-1100nm. Within this region of the NIT spectrum, protein, moisture, oil and starch absorb NIR energy.

Grain is poured into a 500ml sample cup. A blade is inserted across the grain and the excess grain is poured out. The blade is removed from the cup and the 500ml of grain is poured into the sample hopper. The grain is metered through the optical chamber where the NIT spectra are collected and stored in memory. The average of between 10 and 30 spectra are used to compute the percentage protein, oil and moisture. The grain falls into the sample cup which is located on a load cell. The weight of the 500ml of grain is recorded and displayed along with the protein, oil and moisture.
