PCE CSM 7 Colorimeter

PCE CSM 7 Colorimeter

The PCE CSM 7 handheld colorimeter is an optimal solution designed to analyze and comprehensively evaluate color parameters based on international standard color spaces such as CIELabCh*, CIELab*, CIEXYZ, CIERGB, and CIELuv*, along with the ability to determine yellowness, whiteness, and color fastness. The device operates based on standard 8/d photometric geometry, 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 combined with an excitation LED lighting system, along with 2 flexible measuring apertures of 4 mm and 8 mm sizes, supporting measurements on various different surfaces.

Powerful parameter testing performance: Applying advanced signal processing technology with extremely high repeatability (standard deviation within color difference ΔE*ab less than or equal to 0.06), supporting diverse color difference formulas and integrating camera-based positioning for small samples.

Intelligent operation and connection system:

• Automatic calibration: The machine automatically performs white and black calibration upon startup to ensure optimal 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 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 3.7 V Lithium-ion rechargeable battery, supporting more than 3,000 measurements before needing a recharge.
