PCE CSM 4 Colorimeter

PCE CSM 4 Colorimeter

The PCE-CSM 4 handheld colorimeter is an optimal solution designed with a large 20 mm measuring aperture, specialized for analyzing and comprehensively evaluating color parameters based on international standard color spaces such as CIELabCh, CIELab, and CIEXYZ. The device operates based on standard 45/0 photometric geometry combined with a D65 LED light source, helping to perform quick and accurate color tests without affecting the sample.

Outstanding Features

Comprehensive optical measurement system: The device is equipped with a high-quality silicon photoelectric diode sensor along with a standard measuring aperture with a large diameter of up to 20 mm, supporting accurate measurements on various complex surfaces.

Powerful parameter testing performance: Applying advanced signal processing technology with high repeatability (standard deviation within color difference ΔE*ab less than or equal to 0.08), supporting color difference calculation formulas such as ΔE*ab, ΔL*a*b, and ΔECH.

Intelligent operation and connection system:

• Flexible device connection interface: Possesses a user-friendly ergonomic design, supporting automatic white-black contrast calibration to maintain long-term accuracy.
• Combined data processing system: Allows for mass storage directly on the machine with memory storing up to 100 reference samples and 20,000 measured samples, supporting PC connection via USB port with specialized software (CQCS3) to export quality management reports.

Manufacturing materials and durable structure: Sturdy vertical handheld design, making operation easy without needing to place the entire machine on top of the sample.

Energy-optimized operation mechanism: Uses a high-capacity 3.7 V Lithium-ion rechargeable battery (3,200 mAh), supporting approximately 5,000 measurements before needing a recharge.
