What performance does the S400 near-infrared agricultural product quality analyzer have in practice?

The spectral range of the S400 near-infrared agricultural product quality analyzer is 800-2500nm. The S400 belongs to the diffuse reflection type, and its spectral range is 1300nm-2500nm; the S410 belongs to the transmission type, and its spectral range is 900nm-1700nm. The application of near-infrared analysis method to qualitative and quantitative analysis has the advantages of fast analysis speed, simple sample preparation and small amount, multiple analysis can be performed with a single spectrum, no sample consumption and no chemical pollution.

The use of S400 near-infrared agricultural product quality analyzer:
The S400 near-infrared agricultural product quality analyzer can be widely used in the analysis and determination of grains, oilseeds, food, animal feed, textiles, products, industrial products, etc. It is mainly used for rapid non-destructive qualitative and quantitative analysis of the physical properties of liquids, sols without suspended solids, solids, powders, coatings, and other samples.
