Our challenge towards blue economy

The aims of the company is designing, manufacturing and selling instruments for the measurement and the monitoring of oceans and fresh waters.

The top one priority of NKE Instrumentation is to be involved in the understanding of the blue lung of the planet by developing smart high-tech products. The fields of applications are rivers, lakes, estuaries, oceans and deep sea.

There are three distinct ranges of products.

  • Underwater monitoring instruments that are products designed to measure in-situ the main physico-chemical parameters of fresh and sea water
  • Buoys and instrumented systems aim to measure, transmit and retrieve data in any type of environment
  • Profiling floats are used for oceanographic and environmental studies of the evolution of oceans and climate. NKE Instrumentation is though involved in the international ARGO program to supply temperature and salinity profiling floats.

The company is involved in large scale projects that bring together the company's know-how multiplicity from the study to the operational maintenance of the solutions provided. The company's priority is the development of new instruments to contribute to the protection of our environment.

The WiMo and WiMo Plus probes can measure up to 20 water parameters thanks to its new design. The probe is totally plug & play and configurable since it is possible to remove and add sensors as you see need. These sensors can then be calibrated via the tool and the available calibration interface. This probe is very easy to use thanks to the integration of its own web user-friendly interface compatible with any type of device.

The range of autonomous WiFi data loggers is very easy to use and has its own web interface integrated into the WiSens to configure the sensor. In addition to temperature, pressure, conductivity, salinity and turbidity sensors, the range has extended itself and it is now possible to measure tides, waves and also dissolved oxygen. The web embedded interface is very intuitive and allows the configuration and programming of the sensor missions.

The development of the Argo range of biogeochemical profiling floats is one of the company's priorities. This range has extended itself with a profiling float capable of integrating the 6 basic BGC ARGO variables and it is also possible to add other sensors in addition, such as the UVP6-LP sensor which allows the study and quantification of large particles and zooplankton. These profiling floats take advantage of the new graphical interface to define mission and acquisition parameters.

Do you know the WiSens family?

Temperature, pressure, salinity, velocity, tide, waves, conductivity, depth, turbidity … They are not frightened by anything!

Multiparameter WiMo sonde

Up to 20 water parameters

Digital smart sensor suite

Plug and unplug at will

No dedicated software – web embedded interface


A PROVOR NOSS Profiling Float is equipped with NOSS sensor to estimate the anomalies of composition of the seawater. This new profiling float could contribute to improve the knowledge of absolute salinity and density of seawater.

Drifting buoys

This buoy is tailored to measure Sea Surface Temperature, Pressure and High Resolution Sea Surface Temperature!

BGC ARGO Profiling float

This profiling float can be equipped with the 6 basic Argo BGC variables and embed other sensors such as the underwater vision camera for example.

Discover the new pCO2 sensor!

Compact and robust, the pCO2 sensor can measure pCO2 concentration in seawater. The perfect device to measure Air-Sea CO2 fluxes in ocean.


15th Anniversary!!

15th Anniversary!!

It’s already been 15 years now since nke has installed a network of instrumented buoys in front of the EDF Le Blayais nuclear power plant.

These buoys aim to measure temperature in real time from sea surface to bottom, when the Blayais nuclear power plant rejects cooling water in the river.

Mooring tests on oceanographic buoys

Yannick was recently on the field to make some tests regarding our oceanographic buoys.
Those buoys aim to measure in real time the turbidity level at 150 meters below the water surface and 3 meters above the bottom.
