Chroma Color Comparator

The colorimeter calculates color coordinates by measuring the reflectance or transmittance of light from a sample and comparing it with a standard light source. It is used for color quality control in products such as paints and inks, enabling the detection of color differences and consistency.
Selection
When selecting, consider matching the measurement aperture to the sample size, choose between fixed or portable models to suit the scenario, review the instrument's repeatability indicators, confirm compliance with industry standards such as ISO, and evaluate whether the accompanying software functions meet analytical needs.

The necessity of a standard light source box in visual color comparison and color difference assessment of coatings.
In the production of coatings, accurate color evaluation is crucial. Visual color comparison is easily affected by light, as natural light is unstable, and different lighting conditions can make colors appear different.
Visual color comparison method using colorimetric tubes to determine the color phase of varnish.
Colorimetric tube visual colorimetry is a method used to determine the color hue tendency of varnish samples by directly comparing them with a standard color scale using the human eye. During operation, samples and standard liquid columns should be prepared using colorimetric tubes of consistent specifications under standard lighting conditions, and the hue differences should be observed in parallel.
