AF16-F Color Sensor

Single Wavelength VIS Absorption Sensor

High precision sensor for direct installation into pipelines measuring VIS or NIR light absorption of various liquid samples. Wavelength and optical path length can individually configured to meet the process control requirements with the highest accuracy.

Used For

  • Color scales:
    • APHA / HAZEN / Pt/Co color
    • ASTM (D1500) color
    • EBC color
    • ASBC color
    • Gardner (ASTM D1544) color
  • Color control
    • for interface detection
    • in industrial waste water
    • for metal concentration in plating industry
    • of Haemoglobin, e.g., medical / pharmaceutical

The model AF16-F is a single channel absorption sensor designed for inline applications. It accurately measures color or color changes and can be used in a variety of industrial processes, from sanitary CIP/SIP applications to high pressure, high temperature industrial applications. The AF16-F uses light in the wavelength range from 385 to 1000 nm at selected wavelengths. Optical path lengths (OPL) are available from 1 to 1000 mm for process versatility.
