NS800 hand held spectrophotometer uses the principle of combination LED precision spectroscopy, separates the light according to a certain wavelength interval, and adopts groups of sensor array to perform sensitive analysis. spectrophotometers NS800 are a combination of the highest metrological standards and modern trends in the use of electronic devices. The vertical design makes the instrument light and easy to use for measuring even very difficult surfaces. NS800 spectrophotometer with higher accuracy is very sensitive to any colors. It not only can measure L*ab value and delta E value accurately, but also can display spectral reflectance curve which can realize color matching function and calculate the real parameters of various color formulas.

In the R&D process, 3nh scientists and engineers measured various color samples from dark to light, white to black, and other standard color boards provided by ISO (International Standardization Organization). The parameters of test results are integrating with international standards.
3nh also analyzed the parameters from Japan, American and Germany spectrophotometers. The differences of L*ab absolute value between them are within ±1.5. Compared the L*ab value between NS800 and Japan spectrophotometer, when measuring any color objects, the biggest L*ab difference is within ±1.0. This is a breakthrough of 3nh high technology which realizes to be fully compatible with international market.

NS800 spectrophotometer is widely used in plastic, electronic, paint, ink, textile, garment, printing and dyeing, food, medical, cosmetic, industries, scientific research institutes, schools and laboratories. It can measure reflectance spectrum and other color index precisely. NS800 spectrophotometer not only can help to perform color matching and color management studies, but also can control product quality management accurately. The instrument is equipped with high-end color management software which can connect PC to achieve more extension functions.

3nh NS800 portable spectrophotometer serves as a trusted color control tool across many industries:
✅ Plastic & electronics: raw material incoming inspection and finished product color consistency check

✅ R&D laboratories and quality departments for color formulation and documentation



NS800 works best for flat solid samples such as plastic sheets, coated panels, paper, fabric and cosmetic solids. The 45/0 geometry is not recommended for metallic pearlescent paints.
It supports CIE Lab*, LCh, ΔE, whiteness, yellowness and other common color indices.
Yes, it meets CIE No.15, ISO, ASTM and DIN standards for color measurement.
This type of spectrophotometer is engineered for precise color analysis within the coatings industry and built to comply with global industry standards. For automotive coating applications, spherical spectrophotometers with d/8° geometry or multi-angle spectrophotometers featuring 3 to 12 measurement angles are the mainstream choices. Directional 45°/0° spectrophotometers are less commonly used in this sector.
It refers to spectrophotometers dedicated to color testing, manufactured to meet ASTM, ISO and DIN international standards. Before purchase, we recommend consulting color measurement professionals to select the right instrument according to your sample types and required measurement accuracy.
Spectrophotometers typically range from $3,000 to $20,000, which is reasonable considering they are high-precision laboratory-grade instruments. Buyers should stay cautious during selection. A high price tag does not always guarantee superior quality, and low-cost options carry risks. Some suppliers may disguise simple spectrocolorimeters as full spectrophotometers. Currently, many global manufacturers source cost-effective spectrophotometers from China.
Spectrophotometers formulated for general paint applications share similar construction and functions with those used for automotive coatings. Instruments with d/8° optical geometry are most widely adopted. They can test opacity, whiteness index and gloss. Support for SCI and SCE measurement modes is also an essential feature for paint color inspection.
Fundamentally, a spectrophotometer captures spectra within a defined wavelength range. Color spectrophotometers operate in the visible light spectrum, covering 400–700 nm. All other color metrics are derived by converting the original spectral readings into colorimetric values.
With outstanding measurement accuracy and stability, the NS800 enables enterprises to strictly control product color quality, boost competitiveness and win market recognition.
