The 3NH PS808C Coffee Colorimeter is a desktop high-precision colorimeter specifically designed for coffee roasting quality control. It adopts a 45/0 optical geometry and a 50 mm large aperture, suitable for irregular granular samples such as coffee beans and coffee powder. Built-in professional indicators including SCAA, HCCI, and coffee roast degree, it enables one-stop accurate quantitative detection of coffee roast levels.
Built-in dedicated indices such as SCAA, HCCI, coffee roast degree, and CIE LAB color space, enabling users to complete mainstream industry indicator measurements without switching devices.
Equipped with a food-grade 50 mm large measuring aperture, it easily measures coffee beans, coffee powder and other samples, effectively reducing measurement fluctuations caused by uneven particle distribution of samples, delivering stable and reliable data.
Precise acquisition in the 400-700 nm band with a wavelength interval of 10 nm. Real-time display of the professional spectral reflectance curve, making sample spectral characteristics clear at a glance.
Adopting 45° annular uniform illumination and 0° perpendicular receiving geometric optics, matching human vision, and effectively avoiding interference from sample surface texture and gloss.
Supports local storage of 1,000 standard samples and 30,000 test samples. Measurement records are saved at any time, meeting the traceability and analysis needs of large-scale production.
Supports multiple languages including Chinese, English, Russian, etc. Comes with professional quality management software, facilitating data analysis, report export, and multi-scenario applications.
