CONTROS DETECT® incl. real time data visualization, setting of sensor parameters (e.g. measuring intervals, internal data logger settings, sleep mode function) supported by a mission planning tool and data download from internal logger
The advanced, optical sensor is based on the principle of fluorescence quenching. Dissolved oxygen (O2 ) molecules diffuse into a membrane in which a fluorescent dye is embedded. Oxygen is capable of quenching this fluorescence by transferring the excitation energy from the dye to the O2 molecule. The sensor repeatedly excites the dye in the membrane and measures the intensity and phase shift of the fluorescence light. The more O2 is present in the water, the smaller is the measured fluorescence signal and the higher is the phase shift.
Highly efficient fluorescent dye embedded on a curved, solid
substrate to enhance light yield. Very fast response time (t
63 < 3 s) combined with high stability and accuracy. Versatile - easy integration into almost every oceanographic
measurement system and platform. Robust - can be used in water depths up to 6000 meters. Titanium housing with small dimensions. Very low power consumption. Programmable sleep mode extends battery lifetime during
autonomous deployment. Comprehensive software for programming, data download and visualization included. Non-consumptive O2 measurement
