Halogen Concentration
Multi Channel Photometric Converter
The C4000 converter is a multi channel controller capable of operating all optek photometric sensors. The C4000 converter allows for easy programming and operation, and can supply up to four real time configurable 4-20 mA output values correlated to any units of measure. The C4000 offers configurable relay alarms, can record and download process data, and can operate up to four sensors simultaneously.

Dual Channel VIS/NIR Absorption Sensor
he AF26 is a high precision dual channel color sensor for inline operation; the secondary wavelength is designed to compensate the desired light absorbance measurement from any undesired light scattering influence, such as suspended solids, gas bubbles, immiscible fluids or window fouling. The AF26 sensor’s output can be correlated to almost any color scale including APHA and Hazen.
