3nh CR8 Spectrophotometer (Professional Edition)

3nh CR8 Spectrophotometer (Professional Edition)

In industrial manufacturing and coating processing, color consistency between batches is the most intuitive measure of product quality. Evaluating color solely by the naked eye can easily lead to subjective disputes between the production department and customers. The 3nh CR8 Spectrophotometer (Professional Edition) is the ideal digital standardization solution – delivering the high accuracy of grating spectrophotometry technology at an extremely economical price, helping businesses elevate their quality control processes.

Overview of 3nh CR8 Spectrophotometer (Professional Edition)

The 3nh CR8 (Professional Edition) is a portable spectrophotometer line specifically designed for mobile inspection environments in factories and warehouses. The device applies the international standard d/8 optical geometry (diffuse illumination, 8-degree viewing angle), fully meeting the strict regulations of the International Commission on Illumination (CIE).

Thanks to the integration of advanced light-splitting grating technology and a highly sensitive dual-array CMOS spectral sensor, this Professional Edition accurately extracts the reflectance power of each light wavelength from 400nm to 700nm. The machine delivers stable measurement results with excellent repeatability, completely outperforming basic colorimeters that use outdated color filters.

Outstanding Features of 3nh CR8 (Professional Edition)

💡 Accurate Grating Spectrophotometry Technology

Unlike cheap colorimeters that are prone to data drift or large errors, the 3nh CR8 Professional utilizes a premium optical grating system. This technology allows the device to deeply analyze the visible light spectrum, helping to detect the smallest chromaticity deviations and thoroughly preventing metamerism (a phenomenon where colors look identical under one light source but different under another).

💡 Optimal Measuring Aperture and Precise Positioning Capability

The CR8 Professional features a flat standard measuring head design that ensures tight contact with the material surface. Combined with a clear positioning light spot, technicians can easily align the measuring aperture to the exact center of small details on the product without fear of misalignment, ensuring the supreme objectivity of the data.

💡 Simultaneous Integration of Two Advanced Measurement Modes: SCI and SCE

SCI (Specular Component Included): Specially used to measure the core intrinsic color of materials, completely eliminating interfering factors from gloss or roughness on powder coatings and plastics surfaces.

SCE (Specular Component Excluded): Accurately reflects the actual color displayed to the consumer’s eyes, helping to achieve the most flawless appearance evaluation of the product.

💡 Rich Color Spaces and Super-Fast Pass/Fail Evaluation

With just a gentle button press within 1.5 seconds, the sharp LCD color display of the CR8 Professional instantly shows the results:

All popular color spaces: CIE Lab, XYZ, Yxy, LCh, RGB…

Standard color difference formulas: Delta Eab, Delta E00, Delta Ecmc, Delta E94.

Smart warning mode: Automatically compares the measured sample with the standard sample and immediately displays “Pass” or “Fail” based on the allowable Delta E tolerance, helping factory workers quickly screen out defective parts right on the production line.

💡 Smart Mobile App and PC Software Connectivity

The CR8 (Professional Edition) features high-speed Bluetooth wireless technology and a USB-C data port:

• Quickly connects to smartphone applications (App), allowing engineers to easily synchronize data to the cloud, look up and store international color card libraries (Pantone, RAL).
• Instantly shares color inspection reports with partners or supervisors via Zalo or Email directly from the factory floor.
• Easily synchronizes data with color management software on computers to track chromaticity trend charts and automatically export professional quality control reports (QC Reports) in PDF format.
