3nh NS820 Handheld Spectrophotometer (400~700nm; 10nm)

3nh NS820 Handheld Spectrophotometer (400~700nm; 10nm)

In modern industrial quality control processes, evaluating color purely by the naked eye under factory lighting always carries a risk of error due to subjectivity and metamerism (a phenomenon where colors look identical under one light source but exhibit a significant deviation when moved to another). To fully standardize the QC workflow, businesses require a scientific quantitative tool capable of deeply analyzing the spectral structure of color pigments. The 3nh NS820 handheld spectrophotometer is the perfect answer—a premium portable instrument featuring an ultra-fine 10nm spectral pitch interval, helping enterprises master color inspection technology with maximum reliability.

Overview of the 3nh NS820 Spectrophotometer

The 3nh NS820 is a professional handheld spectrophotometer meticulously researched by the 3nh brand to optimize mobile measurement capabilities across factories and warehouses while ensuring accuracy on par with benchtop instruments. The device utilizes an internationally standardized d/8 optical geometric structure (diffused illumination, 8-degree viewing angle), fully and strictly meeting the rigorous regulations of CIE No.15, ISO 7724/1, ASTM E1164, and DIN 5033.

The key feature that places the NS820 at the forefront of the portable market lies in its diffraction grating spectral separation technology combined with a highly sensitive dual-path CMOS matrix sensor. The instrument breaks down light spectral energy from the 400 nm to 700 nm wavelength range with an extremely small pitch interval of just 10nm, helping to detect the smallest micro-shade variations on material surfaces.

Key Features of the 3nh NS820

💡 Ultra-Fine Spectral Analysis Capability (400~700nm; 10nm Interval)

The core strength of the 3nh NS820 lies in its continuous spectral scanning range that completely covers visible light with an ultra-fine 10nm bandwidth interval. This technology allows the device to extract the detailed spectral reflectance curve of materials, completely eliminating errors caused by metamerism and delivering stable measurement results with excellent repeatability over multiple consecutive measurements.

💡 Large Industrial LCD Screen Displaying Intuitive Spectral Graphs

Unlike conventional colorimeters that only display simple digits, the NS820 is equipped with a large, sharp industrial graphic display. Operators can monitor the spectral reflectance curve and multi-dimensional color coordinate deviation charts directly on the device itself without needing a PC connection, providing a highly professional on-site operational experience.

💡 Simultaneous Integration of Dual Premium Measuring Modes: SCI & SCE

The advanced optical system of the NS820 allows technicians to perform deep analysis of material surface characteristics via two measuring modes:

• SCI (Specular Component Included): Measures the actual intrinsic color of the material, eliminating all interference caused by surface gloss or the roughness of powder coatings and plastics.
• SCE (Specular Component Excluded): Measures the actual color appearance as seen by the consumer, perfectly serving product aesthetic evaluations according to real visual perception.

💡 Standard Flat Measuring Aperture and Precise Positioning Illumination

The NS820 features an industry-standard flat measuring aperture (typically configured at Φ8mm), which is the most optimal size for the vast majority of manufactured materials. The flat aperture design allows it to fit completely flush against large, flat product surfaces, eliminating external stray light interference. Combined with a clearly defined illuminated positioning spot, technicians can easily align the aperture with the exact center point to be checked.

💡 Comprehensive Color Spaces and Ultra-Fast Pass/Fail Evaluation

With a single gentle button press taking less than 1.5 seconds, the instrument calculates and instantly displays:

• A complete set of international color spaces: CIE Lab, XYZ, Yxy, LCh, RGB…
• Advanced color difference formulas: Delta Eab, Delta E00, Delta Ecmc, Delta E94.
• Smart tolerance warning mode: Automatically compares the measured sample with the standard sample and instantly displays “Pass” or “Fail” based on the allowable tolerance range, helping assembly line operators rapidly screen for defective parts directly on the floor.

💡 Deep Data Management via PC Software Connection

Via a high-speed USB data transfer port, the NS820 effortlessly synchronizes data with professional PC-based color management software. The software supports businesses in storing tens of thousands of standard sample datasets, managing digital color libraries (Pantone, RAL), tracking shade variation trend charts across production batches, and automatically exporting professional quality control reports (QC Reports) in PDF/Excel formats to send to major partners.

Practical Applications of the 3nh NS820

Thanks to its compact portability, fine 10nm spectral scanning band, and exceptional visual graphic display, the 3nh NS820 handheld spectrophotometer is widely applied across various fields:

• Plastic Industry: Controlling the color uniformity of incoming masterbatch resins, plastic preforms, and the surfaces of large flat molded plastic products such as household plastic panels, TV or refrigerator casings, and automotive plastic components.
• Paint, Coating & Plating Industry: Inspecting color deviations in powder coatings, coil coatings, protective finishes on metal sheets, construction materials, and architectural wooden furniture.
• Printing & Packaging Industry: Checking color variations of printing ink on paper boxes, flat corrugated cartons, and embossed decal labels, ensuring absolute compliance with brand identity logo colors for partners.
• Textile & Leather Industry: Rapidly evaluating color quality, color fastness, and color consistency between flat dyed fabric rolls before moving to mass cutting and sewing lines.
