The AquaSensors RDO Pro DO advanced optical dissolved oxygen sensor, for wastewater monitoring, can be connected directly to a PLC for seamless integration with industrial control systems. It is possible to use any computer to display data, calibrate and customise the measurement without an intermediate analyser electronics box.
An optional AV38 local display/controller is also available for more conventional installations offering single or dual sensor inputs. The system is suitable for monitoring all dissolved oxygen levels throughout a wastewater treatment plant.
Features of the sensor include: 0-20 ppm measurement range; no membranes - only annual field-replaceable caps; resists photo-bleaching and abrasive process media; no ‘poisoning’ by sulfides; no cross sensitivity to carbon dioxide, ammonia, pH, sulfide, sulfate, chloride, or hydrogen sulfide; plug-and-play design with digital network interface.
Typical applications include municipal and industrial wastewater (aeration tanks, aerobic digesters, plant effluent monitoring - NPDES permit holders, anaerobic digesters), aquaculture, brewing, fermentation and bio-processing. Many applications also exist in chemical, process, food and dairy, pulp and paper and other process industries.
