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.
