CHN SPEC DS-816N Bench-top Spectrophotometer (d/0, ΔE*ab≤0.01)

CHN SPEC DS-816N Bench-top Spectrophotometer (d/0, ΔE*ab≤0.01)

CHN SPEC DS-816N Bench-top Spectrophotometer is a premium professional bench-top spectral color measurement instrument manufactured by CHNSpec. The highlight of this model lies in its specialized d/8-degree illumination geometry (noting standard d/0 transmission setup), combined with ultra-high precision and repeatability, providing an excellent color measurement and analysis solution for liquids, films, or transparent materials in laboratories and quality control centers (QC/R&D).

Outstanding Technological Features

Specialized d/0 Illumination Geometry: Unlike conventional reflectance measurement instruments, the DS-816N adopts an optical structure of diffuse illumination and perpendicular 0-degree viewing angle (d/0 degree). This geometry strictly complies with international standards for measuring spectral transmittance and color of translucent/transparent materials, allowing accurate analysis of color properties without being affected by light orientation.

Top-Tier Repeatability (ΔE*ab Less Than or Equal to 0.01): This is one of the key indices demonstrating outstanding hardware stability in the industry today. With an ultra-small repeatable error margin (less than or equal to 0.01) when measured on the standard tile, the device ensures absolute data uniformity across measurements, completely eliminating instrument-induced deviations.

Comprehensive Transmittance Spectral Analysis: The device does not merely conduct basic color measurement, but also captures spectral transmittance across the entire visible wavelength range. It provides crucial indices such as: total spectral transmittance, haze, transparency, Yellowness Index, and Whiteness Index, perfectly meeting strict inspection requirements.

Expanded and Flexible Sample Chamber: The chamber design of the DS-816N is highly spacious and flexible, allowing operators to easily place test samples of various sizes. The instrument accommodates a wide range of liquid cuvettes (cells) from small to large dimensions, as well as specialized fixtures to securely hold glass sheets or thin plastic films.

Premium Dual Light Source System: Utilizes a combination of a long-lifespan Pulse Xenon lamp and full-spectrum LEDs, comprehensively covering the spectrum from 360 nm to 780 nm. This light source offers extremely high stability, generates no heat that could alter the properties of liquid samples, and requires no frequent replacements.
