CHN SPEC DS-807 Spectrophotometer (0–200%, 400–700 nm)
In the manufacturing industries of plastic pellets, food, pharmaceuticals, or chemicals, controlling the color of granular and powder raw materials is always a major challenge due to non-uniform surfaces. The CHN Spec DS-807 color measurement device is a breakthrough solution, specially designed to eliminate optical errors, delivering the most accurate and stable color measurement results.
Why is the DS-807 the Top Choice for Granular and Powder Materials?
Conventional colorimeters often struggle when measuring powder or granular samples due to light leakage and shadowing effects between gaps. The CHN Spec DS-807 completely resolves this problem thanks to: An optimal measuring aperture: Designed to cover a larger surface area, providing a better average color value for loose materials. An airtight measuring chamber: Prevents ambient light interference and protects the sensor from dust contamination from powder samples. Specialized accessories: Comes with a sample cup (cuvette) to help compress and flatten the powder surface, creating ideal measurement conditions. The CHNSpec DB-807 spectrophotometer is specially designed for non-uniform samples such as powders and color masterbatches. With a large 50mm measuring aperture and a fully sealed measuring port as its primary advantages, the device overcomes common industry issues such as large measurement errors and susceptibility to dust accumulation found in small-aperture devices. The device supports color parameter measurements in various color spaces such as CIE Lab and XYZ, accurately recording the core color values of samples as well as color difference data between batches. It is capable of delivering fast results within 1 second and storing 10,000 data entries, meeting the needs of precise laboratory analysis and efficient quality inspection on production lines.
Whether researching powder formulas, calibrating masterbatch color lots, or controlling color in downstream processing stages like injection molding and extrusion, the DS-807 provides stable and reliable color data, assisting businesses in ensuring product quality.
