CHN SPEC CS-720 Haze Meter

CHN SPEC CS-720 Haze Meter

The CHN SPEC CS-720 Haze Meter is a professional benchtop optical measurement device, specially designed for R&D laboratories and high-standard quality control (QC) systems. Unlike basic models that only measure Haze, the CS-720 integrates full-spectrum spectrophotometric technology, making it an “All-in-one” analysis station that perfectly handles transparency, light scattering capabilities, and material color differences.

Outstanding Features

• “All-in-One” measurement: The CS-720 not only provides data on Haze and Total Transmittance. The true power of the device lies in its in-depth color analysis capability, providing parameters such as Lab* color space, LCh, Yellowness Index (YI), Whiteness Index (WI), and liquid color indices (Pt-Co/APHA, Gardner).
• Advanced spectral technology (400 – 700nm): The device is equipped with a spectrophotometric sensor system that scans the entire visible light spectrum. Combined with a high-precision integrating sphere, the device fully captures both transmitted and scattered light signals, maximizing the elimination of environmental optical interference.
• Dual standard system compliance: The device simultaneously meets the strictest testing standards of both ASTM (such as ASTM D1003, D1044) and ISO (ISO 13468, ISO 14782) systems, ensuring that your enterprise’s R&D and QC data is globally recognized and comparable.
• Flexible Open Sample Area: The Open Sample Area design allows for direct measurement of full-size glass panels, long rolls of film, device screens, or the use of cuvettes to measure liquid/chemical samples without size limitations.
• Smart interface & Data management: The CS-720 is equipped with a large color touch screen and an intuitive independent operating system. The device also supports computer connection via USB/RS232 ports, accompanied by dedicated PC software for data storage, tolerance setting, chart analysis, and professional QC report exporting.
