The OxySense range of online DO meters utilizes the very latest and best optical DO sensor available in the world today. It is an optical luminescent device which is extremely resistant to abrasion, extremely stable, and has greatly reduced maintenance and whole life costs.
The OxySense Optical Dissolved Oxygen Meter with self-cleaning and self-verification offers enhanced reliability and unrivaled low maintenance. Optical DO meters have largely replaced electrochemical DO sensors (Clark Cells) due to their better reliability and lower maintenance requirements.
The OxySense DO sensor is available with different controllers giving you the same great performance with different communication, display, and control options. With the OxySense range of online DO meters, you get everything that you need – and nothing that you don’t.
Principle of Operation
The sensing element (lumiphore) is activated, or excited when illuminated with a blue light. When activated, the lumiphore then emits blue light in an intensity that is inversely proportional to the amount of oxygen present in the water. There is also a time delay between the peak emission of blue light and peak response of fluoresced red light. The amount of delay is inversely proportional to the amount of oxygen present. This time delay can be expressed as a phase shift between the wave patterns of incident blue light and the fluoresced red light. This is in turn reported by the electronics into a ppm or mg/l reading of Dissolved Oxygen. The advantages of this technology are that it is more stable than traditional electrochemical devices and far more resistant to abrasion. By using the state of the art sensor and electronics together the reliability, accuracy, and flexibility of the OxySense Meter is far superior to that of its competitors.

What is probably the worlds most reliable Dissolved Oxygen sensor from In-Situ® the RDO® sensor coupled with Pi’s award winning electronics provides up to 12 months between maintenance and calibration events and results in probably the best online DO meter available in the world today.
The self-verification option is revolutionizing calibration routines in that this dissolved Oxygen monitor is able to check it’s own functionality on a regular basis and call for calibration when necessary, typically every 12 months.
- No chemicals or moving parts
- Optional self-cleaning sensor and self-verification
- Stable and reliable – excellent process control
- Suitable for all Dissolved Oxygen applications
- Up to 12 months between maintenance
- No calibration
The OxySense optical sensor is available with different controllers giving you the same great performance with different communication, display, and control options. With the OxySense range of online DO meters, you get everything that you need – and nothing that you don’t.
The OxySense DO Meter is the first of its kind in the world to offer automatic insitu sensor verification as an option. The OxySense DO Meter is able to reduce maintenance by automatically checking it’s sensor operation at user defined time intervals. Calibration on the In-Situ® sensor is normally required only once per annum so with the automatic sensor verification option and the self clean option the sensor may not need to be inspected at all for a full year.
