The Tintometer Colour Discs CAB Hazen/APHA are precision-engineered glass standards designed for accurate visual colorimetric analysis using the Platinum-Cobalt (Pt-Co) scale. Specifically calibrated for the 30–70 mg Pt/L range, these discs are compatible with the Lovibond Comparator 2000+ and Nessleriser 2250 systems. Manufactured with non-fading, UV-resistant glass filters, they ensure consistent and reliable color grading for transparent liquids such as water, oils, and chemicals.
These CAB discs are essential for laboratories requiring precise and reproducible color measurements in the mid-range of the Hazen/APHA scale.
