AquaMS - Dissolved Oxygen Measurement Submersible Probes
Dissolved oxygen in water is a fundamental parameter for the aquatic fauna and flora and the associated organic activity. Indeed, the dissolved O2 level found in lake, river and oceans governs the local environment’s composition. On the other hand, dissolved O2 is also important to optimize biological activity in waste water treatment. Dissolved O2 monitoring allows then both to obtain sufficient quantity for the aquatic wildlife and in natural resources, but also avoid excessive aeration in waste waters.
Dissolved O2 measurement can be done with 2 probes type:
- The MS08 device for a portable or laboratory measurement. This kit contains a reading data box and 2 linked probes. The titanium probe integrates the O2 galvanic micro-sensor et the other probe is a temperature sensor.
- The CTD48 system for an online application in the environment. The probe contains several measuring sensors in its head. The titanium protection cage integrates the O2 galvanic micro-sensor, a pH sensor and a temperature sensor and can also contain a pressure sensor. The measuring data are processed through the embedded electronic in the probe’s body. A CTD48M version is also available for data recording.
- Aquaculture pool monitoring
- Aeration system control
- Waste water and freshwater measurement
- Laboratory measurement
The pervious to gases membrane let the O2 passing through. It is then spread until reaching the working electrode. O2 is reduce, leading to a current depending on oxygen concentration. This current of a few hundred pico-amperes is converted in 0-5 V by the probe electronic.
