Description
Overview
GAOTek food paint portable digital colorimeter is a grating spectrophotometer that the company has spent 3 years to design and is developed by the company independent intellectual property rights. The instrument adopts 1000 lines precision blazed grating as the spectroscopic element, the silicon photocell array with large photosensitive area as the detector, the full spectrum led with high life as the light source, and the optical resolution is less than 10 nm in the visible light range. Under the condition of d or 8 geometric optical illumination recommended by CIE, this product can accurately measure the SCI and SCE reflectance data of samples or fluorescent samples and can accurately measure and express various color difference formulas and color indexes in various color spaces. With this product, it can easily realize the accurate transmission of color and can also be used as the detection equipment of accurate color matching system. This product is also widely used in the color quality control of various products. Digital colorimeter textile food paint portable is equipped with high-end color management software, which is connected to the computer to realize more function expansion. The instrument has stable performance, accurate color measurement and powerful function. It is widely used in plastic electronics, paint and coating, textile printing and dyeing, printing paper, automobile, medical treatment, cosmetics and food industries, as well as scientific research institutions and laboratories etc.
