The AF56-F model is a high precision colour sensor. It measures the attenuation of light through the process fluid. The AF56-F sensor is specially designed for inline installation and is non-invasive.
Its modular structure offers maximum flexibility for direct connection to the production line, without influencing the measurement accuracy. The fluid is crossed by a focused and constant light beam. This measurement of the intensity of the light transmitted in relation to the light emitted allows the monitoring of variations in color or product concentration in line and during production.
By adjusting the optical path, it can detect concentrations in the order of ppm but also in %. The model AF56-F sensor emits light from 385 to 1100 nm and on the detector side measuring at a specific wavelength of 430 nm the light absorption of various liquid samples.
Typical applications: phase separation, OD measurements for the growth of micro-organisms, discoloration monitoring, mixing control, product colour management (APHA / HAZEN, ASTM, Saybolt, etc.)
