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. Some products are able to study mudflats or beach level variations. Some devices are adapted to fishermen as they measure and record tractive forces in fishing structures and hook timers measures the time ran out between the moment the fish swallowed the hook and the halving of the line.

AirCorr: Corrosion

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.
