The Lovibond visual colorimeter uses a series of Lovibond standard color palettes. Under appropriate illumination, the white reflective surfaces of adjacent sample and comparison fields are observed through a tube. The standard color palette is moved into the comparison field using a simple sliding frame, and the user can compare the color of light passing through the standard color palette with the color of light transmitted through or reflected from the sample. For samples that are too light to measure, the sample color can be darkened by moving it into a neutral color standard dial before measurement. Move the slider until the color on the standard color palette matches the color from the sample, thus obtaining the chromaticity value.
Simple instrument maintenance ensures its excellent performance.
Lovibond visual colorimeter is a precision optical instrument that should be kept clean to ensure its performance, especially under harsh operating conditions.
Easy to clean and maintain
When the sample overflows, the white liner in the sample slot can be easily removed for cleaning, keeping the interior white and ensuring measurement. If necessary, it is also very convenient to clean and replace the glass sheets in the standard chromaticity plate holder.
The Model F series visual colorimeter is widely used. In addition to measuring transparent samples, it can also determine opaque solids, powders, and gelatinous substances. Optional accessories for solid samples can be used to measure samples with light reflection. By making slight adjustments to the instrument configuration, it can accommodate different applications and chromaticity standards.
Model F Standard Type Determination of Fat Fat Oil Bleached Cordyceps Liquid Chemical Reagent Drug
Model F is a new product in the famous Lovibond colorimeter series, using the Lovibond chromaticity standard that has been in use for centuries. Its modern craftsmanship improves the traditional visual colorimetric method. The standard glass color plate is embedded one by one in a durable nylon bracket, which can effectively protect the plate, and adjacent color standards are easy to distinguish. Adopting an improved optical prism system that produces excellent color matching and repeatability. The field of view is evenly divided, and there is a clear dividing line between the sample viewing area and the color chart viewing area, which helps to distinguish chromatic differences. The diffuse tungsten lamp light source meets the lighting standards. The white pad inside the sample tank can be replaced at any time, and it is equipped with a sample tank to ensure the correct position of the sample tank.
