In-situ Fluorescent optical DO Detection
OptoDOSys_M is an Optical DO sensing system from MJK & Insite lG, ideal for use in wastewater treatment works. The technology is based on the quenching of Ruthenium salt fluorescence by the presence of Dissolved Oxygen. Because it is "Non consumptive", it does not require movement of the medium past the sensor.
It is also very accurate at low DO levels and because of this feature, is useful in anoxic and anaerobic sections. The sensor design together with optional air/liquid cleaning reduces maintenance to a very low level, and the 5 yr sensor warranty guarantees your low cost of ownership.
Because this system uses the Insite IG optical DO sensor, you won't have to change end caps, membranes or consumables. The sensor is not affected by ambient light or harmed by drying out because of the solid state technology.
You can link the optical DO sensor to a MJK transmitter/display making great use of this versatile unit. The transmitter includes data logging for up to 30000 time stamped readings and has a real time graphic display. You may download data to a computer via a USB using the free MJK software.
Other outputs include 4-20 mA analogue signal, 2 relays and modbus for direct Scada link (PROFIBUS converter available on request). You can network multiple units, including other instruments in the range (magflux and DO), for common display.
We regularly supply this sensor and transmitter combination to UK water companies and contractors. The system is flexible enough for contractors to integrate it into their own installation plans. We also provide a bespoke option where we can supply you with a complete system including a cleaning compressor in a housing for quick installation on site.
