Description
Overview
GAOTek grating industrial colorimeter advanced utilizes a 45 or 0 geometric optical structure, following CIE No. 15 standards. Employing concave grating spectrometry, it accurately measures sample reflectance and various colorimetric data. The instrument is equipped with 0.31 in (Φ8 mm), double measuring apertures, making it ideal for traffic signs, precise colour measurement, and quality control in various industries. Additionally, it features a separate UV source for fluorescence sample measurements. Elevate your colour analysis capabilities with grating colorimeter, ensuring accuracy and versatility in a range of applications.
