Rice grain coloriMeter

The rice grain colorimeter captures the reflected light from the surface of an object through an optical sensor and converts color information into digital signals. It is used to detect the color uniformity of agricultural products such as rice grains and grains, aiding in the assessment of product appearance quality during grain processing and quality control.
Selection
When selecting, pay attention to the matching of the measurement aperture with the grain size to ensure the instrument can stably conform to curved surfaces. Verify the validity of the whiteboard calibration certificate and prioritize dustproof and waterproof models to suit the processing environment. Compare the repeatability data of different brands in brown rice and white rice modes, and confirm that the supporting software can export standard chromaticity charts.
