Each of the five different types of water level loggers available from Diver® is unique and designed for a specific function. Diver is the only range of water level logging instruments to include fully ceramic units, the Cera and CTD Divers. Being ceramic, these Divers are fully corrosive resistant, even in the harshest environments
Yes they are more expensive initially but in the long run represent good value for money because they will continue to deliver accurate water level measurements, even in seawater. Crevice corrosion is a very real issue even with the best of stainless steel types. Other, coated water level logger products still use stainless steel in the wetted areas and these will also be susceptible to corrosion in the vital areas.
