Spectrophotometers Traffic Sign BT4580

The BT4580 plus high-precision color colorimeter adopts the 45/0 (45 degree circular illumination, 0 degree reception) geometric

optical structure in accordance with CIE No.15, and adopts the concave grating spectral method, which can accurately measure the sample

reflectivity and various chromaticity data. Equipment Φ 20mm large measuring caliber, used for accurate color measurement and quality control in traffic signs, plastic electronics, paint and ink, textile and clothing printing and dyeing, printing, ceramics and other industries. The instrument has a separate UV light source, which can be used for fluorescence sample measurement. The instrument is equipped with GB 2893 and GB/T 18833 standard colors. The polygonal rectangle tolerance can be manually customized, and the brightness factor and chromaticity coordinate measurement of traffic signs, markings and reflective film can be achieved with one button. For uneven samples or granular samples with stripes, the instrument has high accuracy and high stability.Under the 45/0 geometric optical illumination condition recommended by CIE, the instrument can accurately measure the reflectance data of samples/fluorescent samples, and can accurately measure and express various color difference formulas and color indexes in various color spaces. With the help of this instrument, accurate color transmission can be easily realized, and it can also be used as a detection device for accurate color matching system. The instrument is also widely used in color difference quality control of various products. The instrument is equipped with high-end color management software, which can be used by connecting

computers to achieve more function expansion.
