PCE CRM 40 Chroma Meter

PCE CRM 40 Chroma Meter

The PCE CRM 40 chroma meter is an optimal solution designed to comprehensively evaluate optical parameters of light sources (especially LEDs) in the wavelength range from 360nm to 780nm. The device operates based on international colorimetric standards such as the CIE 1931 and CIE 1976 color charts, helping to perform quick and accurate tests without affecting the sample.

Outstanding Features

Comprehensive optical measurement system: The device is equipped with high-quality silicon photoelectric sensors and advanced spectral filter circuits, ensuring accurate collection and analysis of parameters such as color coordinates, RGB color space, dominant wavelength, and correlated color temperature (CCT).

Powerful parameter testing performance: Measuring illuminance in a wide range from 0.1 to 150,000 lux, providing reliable evaluation of light source quality with high repeatability and accuracy.

Intelligent operation and connection system:

• Convenient handheld design: Ergonomic style for easy one-handed operation, with an intuitive color LCD screen.
• Flexible storage and connection: Integrated SD card slot and USB communication port with specialized computer software for effective data management and report exporting.

Manufacturing materials and durable structure: The machine housing is made of high-grade plastic with a sturdy design, providing high resistance in industrial production environments and laboratories.

Energy-optimized operation mechanism: Uses a high-capacity rechargeable Lithium-ion battery for up to 12 hours of continuous operation.
