CHNSpec DB-807 spectrophotometer is specially designed for uneven samples such as powder and color masterbatches. With a 50mm large measurement aperture and a fully sealed test port as its core advantages, it addresses the industry pain points of large measurement deviations and easy dust intrusion in small-aperture instruments. The instrument supports multi-color space parameter measurement such as CIE Lab and XYZ, accurately capturing the basic color values of samples and color difference data of different batches. It can quickly produce results in 1 second and store 10,000 pieces of data, meeting the needs of precise analysis in the laboratory and efficient quality inspection on the production line. Whether it is powder formula research and development, batch calibration of color masterbatches, or color control in downstream processing links such as injection molding and extrusion, it can provide stable and reliable color data support, helping enterpri
