PCE CSM 20 Colorimeter

PCE CSM 20 Colorimeter

The PCE CSM 20 spectrophotometer colorimeter is an optimal solution designed to analyze and comprehensively evaluate color parameters based on international standard color spaces such as CIE Lab, XYZ, Yxy, LCh, CIE LUV, and Hunter LAB. The device operates based on standard 8°/d photometric geometry combined with an integrating sphere, supporting both SCI and SCE reflectance modes, helping to perform quick and accurate color tests without affecting the sample.

Outstanding Features

Comprehensive optical measurement system: The device is equipped with a 256-pixel CMOS image sensor combined with a 4-color LED system (including UV) and a concave diffraction grating, ensuring absolute accurate collection and analysis of spectral reflectance in the 400nm to 700nm range.

Powerful parameter testing performance: Applying advanced signal processing technology with extremely high repeatability (standard deviation within color difference less than or equal to 0.06), supporting diverse color difference calculation formulas (Δ E) and intuitive PASS/FAIL evaluation.

Intelligent operation and connection system:

• Camera-based sample positioning: Integrates a camera to support precise identification of the exact measurement spot on small samples easily.
• Flexible device connection interface: Possesses a sharp 3.5-inch TFT capacitive touch screen combined with an intuitive interface, making white/black calibration and parameter setup easy right at the field.

Combined data processing system: Allows for mass storage directly on the machine with a large memory storing up to 2,000 reference samples and 20,000 measured samples, supporting PC connection via USB port with specialized software to export quality management reports.

Manufacturing materials and durable structure: Sturdy handheld ergonomic design using high-grade materials, helping to maintain stability in laboratory and production workshop working environments.

Energy-optimized operation mechanism: Uses a high-capacity Lithium-ion rechargeable battery, with a light source lifespan of over 3 million measurements.
