Overview
The Automatic Colorimeter is a high-performance optical instrument designed to accurately measure color, brightness, and whiteness of materials using the light reflection principle. This advanced testing device is widely used in industries such as paper manufacturing, ceramics, cement, minerals, powders, and chemical materials to evaluate product quality and maintain consistent color standards.
Equipped with modern mechatronics technology, the instrument enables one-click testing of whiteness and chromatic values, making color analysis simple, fast, and reliable. The built-in intelligent system allows users to store reference samples, export test results, and monitor quality data efficiently.
Applications
The Automatic Colorimeter is suitable for testing a wide range of materials, including:
Paper, cardboard, and pulp
Ceramic products and building materials
Cement and mineral powders
Starch, calcium carbonate, talcum powder, and other industrial powders
Non-metallic mineral products
This instrument is ideal for quality control laboratories, research institutions, and manufacturing plants that require precise color evaluation.
Key Measurement Functions
The instrument supports multiple advanced color analysis functions:
Measurement of reflected color and chromatic aberration
Determination of D65 brightness (R457 blue whiteness)
Detection of fluorescent whitening agents
Measurement of CIE whiteness and Gantz whiteness
Whiteness testing for ceramics, building materials, and minerals
Hunt Lab and CIE Lab color system analysis
Measurement of yellowness index and ink absorption value
Determination of opacity, transparency, light scattering, and light absorption coefficients
These functions make the Automatic Colorimeter a versatile solution for professional color and brightness analysis.
