CHN SPEC CS-810 Spectrophotometer

CHN SPEC CS-810 Spectrophotometer

The CHN SPEC CS-810 Spectrophotometer (Transmittance Spectrophotometer) is a leading color and transmittance analysis solution for laboratories. Unlike models that primarily measure surface reflectance, the CS-810 focuses entirely on evaluating the color, haze, and light transmittance of liquid samples, films, glass, and transparent plastics.

Outstanding Features

• Specialized D/0 optical system (Transmittance): The device uses a diffuse illumination geometric structure with a 0-degree receiving angle (D/0). This design complies with international standards for color and transmittance measurement of materials that are not completely opaque.
• Diverse measurement of specialized indices: The CS-810 not only measures standard Lab* color values but also integrates specialized scales for the chemical and liquid industries such as: Pt-Co/APHA/Hazen, Gardner, ASTM, Saybolt color scales, and Haze.
• Outstanding accuracy and stability: The device is equipped with a wide-band spectral sensor from 360-780nm and a full-spectrum LED band, delivering excellent repeatability at dE*ab ≤ 0.015 and data processing capabilities with high wavelength resolution, ensuring measurement results are always accurate and reliable.
• Expanded and flexible measurement chamber: The sample placement area is spaciously designed with no overhead space limitations, allowing users to easily place cuvettes of varying thicknesses (from 10mm, 20mm to 50mm, 100mm) or large-sized glass plates and films.
• Powerful data management: The device connects to management software on a computer (PC), helping users perform in-depth analyses, draw spectral graphs, set Pass/Fail tolerances, and professionally export laboratory-standard reports.

Technical Specifications:

In addition to measuring the transmittance of materials, the instrument can also measure the APHA / Pt-Co and Gardner color scales of products such as plastics, solvents, acids, perfumes, and varnishes. It is also used to measure the Saybolt chromatic scale of gasoline, white oil, kerosene, and lubricating paraffin oils. The technology eliminates the subjectivity of visual color evaluation and provides better sensitivity and maximum repeatability.
