Evaluation and calibration of marine sensors
The laboratory for evaluation and calibration of marine sensors and probes is COFRAC accredited for Pressure and Temperature ; it also takes into account measurements such as Marine Currents, Swell, Sound Speed in water, Voltage, Elecric Resistance, Dissolved Oxygen, Turbidity, Chlorophyll, Nitrate... It is also equipped and now experienced in the evaluation of the influence of various sea water parameters on the accuracy of marine sensors and in the development of new calibration methods.
