CHN SPEC DS-812N Bench-top Spectrophotometer (d/0, ΔE*ab≤0.015)

CHN SPEC DS-812N Bench-top Spectrophotometer (d/0, ΔE*ab≤0.015)

CHN SPEC DS-812N Bench-top Spectrophotometer is a premium, professional laboratory-grade color measurement instrument developed by CHNSpec. Featuring a specialized d/0° illumination/viewing geometry and ultra-precise repeatability, this device provides the ultimate solution for measuring and analyzing color and transmittance of transparent materials, thin films, or liquid samples in laboratory and quality control (QC) environments.

Outstanding Technological Features

Specialized d/0° Illumination/Viewing Geometry: Unlike surface reflectance colorimeters, the DS-812N utilizes a diffuse illumination and 0-degree normal viewing (d/0°) optical structure. This configuration is specifically engineered for transmission samples, allowing accurate analysis of the true color characteristics and transparency of materials without being affected by the light source direction.

Ultra-Stable Repeatability (ΔE*ab ≤ 0.015): The repeatability standard deviation between measurements reaches an exceptionally low level (≤ 0.015) when tested on a standard white plate. This index confirms the extreme reliability and high stability of the hardware system, giving businesses peace of mind regarding the consistency of measurement results even through multiple continuous tests.

Comprehensive Multi-Index Transmittance Measurement: The device does not just measure standard color; it performs deep analysis on spectral transmittance data. It provides crucial industrial indices including: Total Transmittance, Haze, Transparency, Yellowness Index, and Whiteness Index.

Spacious and Flexible Sample Chamber: The open-design measurement chamber allows operators to easily handle samples of various sizes. The instrument is highly compatible with a wide range of liquid measurement cuvettes (cells) from small to large capacities, as well as specialized fixtures to secure glass plates, plastic sheets, or thin films.

Superior Combined Light Source System: The device utilizes a combination of pulsed Xenon lamps and a full-band LED system, ensuring comprehensive coverage of the visible wavelength range from 360 nm to 780 nm. This light source offers a long lifespan, excellent stability, and generates no heat that could alter the natural properties of sensitive liquid samples.
