Deploying a HOBO water level data logger in salt water
316 Stainless Steel has good corrosion resistance but it can be damaged by crevice corrosion in saltwater. The stainless steel versions of HOBO data loggers should not be deployed for more than 6 months (lifetime cumulative) in salt or brackish water, or the housing will eventually fail and water will damage the electronics. How long the data logger will last depends on many factors such as salinity, level of dissolved oxygen, and temperature. Biofouling can also limit deployments in saltwater, because growths on the pressure sensor will change its calibration.
