This application is the key activity of NKE Instrumentation as it proposes best quality and very robust products that are equipped with proefficient anti-fouling protection. NKE offers a wide range of sensors among them full autonomous data loggers. There are also dedicated and specific measuring instruments to measure sedimentation, wave tide and much more parameters. NKE is also capable to furnish real-time monitoring to measure the physico-chemical parameters of water or current parameters thanks to instrumented buoys.
ALTUS: Siltation, Sedimentation, Erosion
Description - Altus permits to study mudflats or beach level variations according to tidal currents and swell. This high frequency acoustic data logger is equipped with a 2 MHz transducer located on a light frame at a given distance from the seabed. Altus can be used as tidegauge thanks to its accurate pressure sensor. The parameter setting and reading of the Atlus are carried out using a Data Pencil connected to the serial link of a PC computer. All the command functions are available in the Winmemo II software supplied with the Data Pencil.

SMALL Coastal Float
Description - The small coastal float allows to easily deploy a multiparameter probe SAMBAT at sea or on the water surface. It provides protection against shocks and reduces the development of biofouling on the multiparameter probe. When the probe is mounted on the float, the various sensors of the multiparameter probe are located one meter below the water surface. The operation of removing putting back the mechanical set “SAMBAT support pole” does not require any tool which allows fast, practical and easy maintenance.

PCO2 CARIOCA Buoy
Description - CARIOCA is an automatic drifting or fixed buoy designed to measure the concentration of pCO2 at the surface of the ocean in order to qualify the CO2 exchange between atmosphere and ocean. Moreover, to enable correlation the buoy is fitted with sea surface temperature (SST), practical salinity, fluorescence and dissolved oxygen measurements. It also includes ARGOS transmission equipment and power supply to achieve one year of operating autonomy with measurements every hour. The body of the CARIOCA buoy consists of a tube (0.20m in diameter and 2.5m in length). A wider yellow floating body surrounds the upper part of the tube. The total weight of the buoy is about 130 kg.
