Name: CHNSpec CS-220 Colorimeter Brand: CHNSpec Origin: China Model: CS-220 Suitable for industries: Plastic, Printing, Paint, Textile, Dyeing, and other color management applications. Key Features: Capable of measuring whiteness and yellowness; supports Hunter and Ganz whiteness values, as well as YI (Yellowness Index). Colorimeter is widely used in various fields such as plastic, paint, printing, and textile. It measures sample color data using L*a*b*, L*c*h*, ΔE, and ΔLab according to the CIE color space. 1. Introduction The device uses a sensor from Japan and an information processing chip from the USA, ensuring accurate optical signal transmission and stable electrical signals. The display accuracy is 0.01, and the repeated test accuracy ΔE deviation is below 0.08. 2. Multiple Color Space Display The colorimeter features built-in programs that support L*a*b*, L*c*h*, and Yxy color space displays. This allows it to be used across multiple industries without manual conversion of measurement data, significantly improving work efficiency. 3. Whiteness and Yellowness Testing Whiteness: Hunter and Ganz whiteness; Yellowness: YI (Yellowness Index). 4. Ergonomic Design The instrument is designed with a curved shape based on human palm size, allowing for extended use. The premium leather design increases grip, preventing fingers from slipping during testing. 5. Free Color Management Software Allows real-time evaluation of whether the sample meets standards, generates reports, and stores color data—ideal for enterprises to evaluate and control color data effectively. 6. Manual Input of Standard Sample Data Users can manually input standard samples to perform color difference tests even when no physical sample is available. 7. Large Storage Capacity Can store up to 100 standard sample groups, with each group containing 100 sample data entries. 8. Multi-point Measurement and Average Value Calculation Measures multiple points on the sample and calculates the average value, ideal for color control where the color is not uniform. 9. Key Advantages CS-220 includes a specular component excluded (SCE) measurement mode, making it particularly suitable for measuring and managing color data of powders, colloidal materials, and high-reflective surfaces.
