3nh TS7020 Spectrophotometer (Dual-24 array sensor; ΔE*ab 0.08)

3nh TS7020 Spectrophotometer (Dual-24 array sensor; ΔE*ab 0.08)

In industrial manufacturing quality control processes, color consistency across batches is a decisive factor in a company’s reputation. Using old-generation conventional colorimeters often leads to significant errors when factory temperature conditions fluctuate or material surfaces have varying gloss levels. The 3nh TS7020 portable spectrophotometer emerges as a breakthrough solution in the mid-range segment – delivering high-precision optical grating light-splitting technology, helping businesses digitize colors accurately and quickly with an exceptionally reasonable investment cost.

Overview of 3nh TS7020 Spectrophotometer

The 3nh TS7020 is a professional portable spectrophotometer maximumly optimized for performance-to-cost ratio. 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) and the ISO 7724 standard.

The core power that allows the TS7020 to excel in its segment lies in its Dual-24 Array Sensor system. The device smoothly separates visible light energy across the 400nm to 700nm wavelength range, delivering measurement results with outstanding repeatability and a stable color inspection tolerance of ΔE*ab 0.08.

Key Features of 3nh TS7020

💡 Stable Dual-24 Array Sensor Technology

Completely distinct from cheap colorimeters on the market, the TS7020 features a dual-row CMOS matrix sensor system with 24 independent filtering elements. This technology enables the device to capture color data in parallel, automatically compensate for ambient temperature variations, and completely eliminate interference from external stray light. Consequently, the device achieves high accuracy with a repeatability error of ΔE*ab of just 0.08 over multiple consecutive measurements.

💡 Standard Flat Measuring Aperture and Precise Positioning

The TS7020 features a standard flat measuring head with a commonly used measuring aperture, allowing the device to make tight contact with the material surface. Combined with a clear illuminating indicator line, technicians can easily align the measuring aperture to the exact center of product details without fear of misalignment, ensuring the highest objectivity of inspection data.

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

Despite being in an economical mid-range segment, the TS7020 is still favored with both advanced measurement modes:

• SCI (Specular Component Included): Measures the core intrinsic color of the material, completely eliminating interfering effects from the gloss or roughness of powder coatings and plastic surfaces.
• SCE (Specular Component Excluded): Accurately reflects colors according to the exact visual perception seen directly by the human eye in reality, serving well for product appearance evaluation.

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

With just a single operation taking less than 1.5 seconds, the sharp LCD screen of the TS7020 instantly displays intuitive results:

• Full range of international color spaces: CIE Lab, XYZ, Yxy, LCh, RGB…
• Standard color difference formulas: Delta Eab, Delta E00, Delta E*cmc.
• Smart warning mode: Automatically compares the measured sample with the standard sample and instantly displays a Pass or Fail result based on the allowable tolerance, helping factory operators quickly screen out defective parts directly on the production line.

💡 Powerful PC Software Connectivity

Through the USB data transmission port, the TS7020 easily connects to advanced color management software on computers. This feature helps businesses store thousands of standard samples, manage color card libraries (Pantone, RAL), track chromaticity trend charts of production batches, and automatically export professional Quality Control Reports (QC Reports) in PDF format to send to partners.
