3nh TS-23C spectrophotometer is a standard spectrophotometer that using a 45/0 optical geometry and features planar grating spectral splitting technology and a silicon photodiode array (dual array of 40 groups) sensor, ensuring stable performance. Capable of full-band spectral analysis from 400 to 700 nm。It can accurately reproduce the true colors of plastics, textiles, and various paint coatings, avoiding metamerism and making the measurement results more reliable. Instrument inter-machine variation is strictly controlled within ΔE*ab≤0.2 ,to ensure color consistency between the production line and the global supply chain. It is widely used in industries such as plastics and electronics, paints and inks, textiles and clothing printing and dyeing, printing, and ceramics for precise color measurement and quality control.
Optical geometry: It adopts a 45/0 optical structure (45° ring-shaped illumination and 0° reception), Eliminating orientation dependence significantly reduces interference from the texture of matte and textured materials, making the measurement results closer to the actual perception of the human eye.

Industry Standards: Compliant with multiple authoritative standards including CIE, ISO, ASTM, and national standards, ensuring accurate measurement specifications.

Repeatability accuracy: using dual-array 40-group silicon photodiode sensor,It achieves fine spectral dispersion and high-sensitivity photosensitive acquisition across the entire 400-700nm wavelength range, providing core technical support for the instrument's ultra-high repeatability accuracy of ΔE*ab≤0.022, restoring subtle color differences in samples, and meeting the color control needs of high-precision industries.
Inter-station consistency:The difference between production lines is controlled within an ultra-small range of ΔE*ab≤0.2, ensuring that color standards remain consistent across multiple production lines, workshops, and regions, thus meeting the comprehensive quality control needs of large enterprises and supply chain factories.

Rich color space:CIE LAB、XYZ、Yxy、LCh、CIE LUV、s-RGB、HunterLab、βxy、DIN Lab99、Munsell (C/2) Multiple color spaces,Meets the requirements of different industry standards.
Supports 8 color difference formulas:ΔEab、ΔEuv、ΔE94、ΔEcmc(2:1)、ΔEcmc(1:1)、ΔE00、DINΔE99、ΔE (Hunter), Adaptable to color difference assessment in different scenarios.

Supports observation of 41 light sources:It covers 41 evaluation light sources and simulates color performance under different lighting environments.

User-friendly interface: Equipped with a 3.5-inch TFT true-color capacitive touchscreen, it can display spectrum/data, sample colorimetric values, color difference values/graphs, pass/fail results, color simulation, Color Offset, and other results to meet diverse industry needs.
Portable design:It features an ergonomic and lightweight design, making it comfortable to hold and easy to carry to workshops, outdoor testing sites, and other measurement scenarios.
Long battery life: With a built-in high-performance lithium battery, it can perform 10,000 tests in 8 hours, meeting the needs of long-term continuous operation.
High measurement efficiency:A single measurement takes approximately 1.5 seconds, balancing accuracy with measurement speed.

Dual-caliber configuration: Equipped with dual-aperture (10mm platform + 5mm platform), it can flexibly adapt to large and small size samples.
Multi-industry adaptation:Used for precise color measurement and quality control in industries such as plastics and electronics, paints and inks, textiles and apparel printing and dyeing, printing, and ceramics.

FAQs About Portable Spectrophotometers
Colorimeters is a color measurement device that are used to capture, communicate, and evaluate color. Colorimeters are more affordable, portable, and easier to use, making them a suitable choice for basic color measurement applications, ideal for quick and routine tests.
spectrophotometers offer higher precision and comprehensive data analysis, are better for research, development, and when dealing with complex or highly precise requirements. The biggest difference is in capability and usage. Spectrophotometers are incredibly powerful and can offer more in-depth color measurements than a colorimeter, such as spectral data.
Colorimeters are primarily used for color quality control, while spectrophotometers are used for analysis and formulation. You can choose the appropriate color measurement equipment according to your application needs.
