(DO) dissolved oxygen measurement technology

Dissolved oxygen sensors use an optical technique called fluorescence technology, which does not consume oxygen like all standard membrane sensors. The optical oxygen sensor does not require sensor caps, membranes, filling solutions or routine calibration and maintenance. Our continuous DO sensors come standard with ¼” O.D. tube connectors for integrated jet cleaning and 10 m (33ft) of sensor communication cable. Additional cable length is available on request.
