Lovibond comparator 3000 series visual colorimeter
1、 Product Introduction:
The 3000 series colorimeter is a three field colorimeter designed specifically for visual measurement of chromaticity grading. The instrument is equipped with one colorimeter on each side, and users can compare the two colorimetric discs of the standard sample simultaneously by rotating the left and right knobs to obtain the value of chromaticity grading. Widely used in industries such as petroleum, chemicals, and food.
The 3000 series includes multiple specific models, including Gardner colorimeter, FAC dark fat colorimeter, US military resin colorimeter, EBC beer colorimeter, and ASTM D1500 petroleum colorimeter. Each colorimeter comes standard with a corresponding glass colorimeter. The halogen tungsten lamp meets the CIE C standard light source requirements. For the AF607 EBC colorimeter, according to relevant standards, the CIE B standard light source is used to ensure a constant light source condition during chromaticity measurement, whether it is day or night, and is not affected by external environment.
2、 Product Features:
1. Three field visual color comparison for easy chromaticity grading
2. Glass color chart, non fading
3. Specialized colorimetric tube or colorimetric dish, easy to operate
4. For certain models, standard filters or chromaticity standards can be selected
Observing the sample and two adjacent color chips simultaneously makes it easier for the operator to obtain matching chromaticity values. According to the quality control requirements of certain industries, it is necessary to control the color of the product within a certain range. The color chart can be set at two color limits to quickly determine whether the sample meets the standards.
The instrument is equipped with a CIE C standard light source * to ensure a constant light source condition during chromaticity measurement, whether it is day or night, and is not affected by external environment.
*For AF607 EBC colorimeter, according to relevant standards, CIE B standard light source is used.
