Versatile technology


Superior technology for large AND small

sample sizes. The patented instrument is

the grain industry’s superior NIR analyzer specifically designed for and proven to

provide accurate analysis of small sized samples (100 or down to 20 grams).

Simple to Use – Easy to Operate

The SEED-WATCH® NIR-50 requires no special skills to operate. Simply pour the

whole grain sample to be analyzed into

the sample holder, and place the cup into

the analyzer. No special sample preparation

is needed. The sample is not damaged in any way. There is no waste or chemical by-products.

Once activated, the SEED-WATCH® NIR-50 quickly measures the grain’s protein, moisture, and oil concentrations and displays them on the LCD display or prints on the optional printer.


How it works


The analyzer works with “Diffuse Transmittance”, a principle where the light energy that enters the sample is scattered and absorbed within the sample. The spectra exiting the sample, and directly displays the product constituent concentrations
