Description
Overview
GAOTek portable spectrophotometer colorimeter uses 45 or 0 (45-degree ring illumination, 0-degree reception) geometric optical structure in accordance with CIE No. 15 and adopts concave grating spectrometry to accurately measure sample reflectance and various colorimetric data; The instrument is equipped with 0.31 in, 0.15 in (Φ8 mm, Φ4 mm) double measuring aperture, used for traffic signs and accurate color measurement and quality control in various industries. It has a separate UV source for fluorescence sample measurements. The grating spectrophotometer can easily achieve the accurate transmission of color and can also be used as the detection equipment of the accurate color matching system; it is used for accurate color measurement and quality control of traffic road signs, plastics, electronics, paint and ink, textile and garment, printing and dyeing, ceramics and other industries. The instrument has a separate UV light source for fluorescent sample measurements.
