Besides the usual parameters, the society develops, manufactures and sells specific loggers able to measure and record specific parameters. NKE Instrumentation has a great expertise in high resolution density and absolute salinity as well as in pCO2 concentration in seawater.
NOSS: density and absolute salinity
Description - NOSS sensor is a unique underwater sensor for in situ refractive index measurement and capable to detect salinity anomalies of seawater. NOSS sensor has been designed for an use even in harsh environments, down to 2000 meters.

SPCT: Corrosion
Description - The SPCT data logger allows the in situ recording of temperature and corrosion potential between a test point that is made of an immersed metallic structure and a measuring electrode in zinc.

SCPC: Determination of the Cathodic Protection
Description - The SCPC logger provides in situ the value of current density necessary to protect an immerged metallic structure. It allows to determine the characteristics of the cathodic protection needed such as size, number of sacrificial anodes or power supply.

AirCorr: Corrosion
Description - AirCorr measures and registers the change over time in the electrical resistance (ER) of a thin metal track applied on an insulating substrate. If the metal corrodes, the cross-selectional area of the track decreases and the ER increases. The changes in ER can be directly translated into corrosion depth and corrosion rate.
