AF333 provides visual iodine-colour measurement from yellow to brown to DIN 6162 across 1–300 mg/100 ml for solvents, plasticisers, resins, oils and fatty acids.
Key features
- An integrated prism brings the sample and comparison fields together for colour discrimination; ultrasonic sealing protects the optics.
- Calibrated glass standards represent discrete, colour-stable grades for direct sample matching.
- Three iodine discs cover 1–300 mg/100 ml; use the 10 mm or 25 mm cell appropriate to the scale range.
- The supplied Daylight unit provides consistent illumination and reduces the influence of changes in ambient lighting.
