Optek Model AF26 dual-channel absorption sensor

The Optek Model AF26 is a dual-channel absorption sensor designed to automate manual processes and offer increased control of inline applications. It precisely measures color and concentrations, and can be used in a variety of industrial processes.The AF26 sensor uses light at wavelengths of 380 to 1,100-nm and is available in a wide variety of line sizes, process connections and wetted materials. Construction is Type 316 stainless steel,to accommodate applications ranging from clean-in-place (CIP) and steam-in-place (SIP) to extremely high-pressures (up to 325 bars), high-process temperatures (up to 464°F), and can meet all hazardous area classifications. The optical windows are made of single-crystal sapphire and provide superior resistance to all abrasive and corrosive media.
