Cera-Diver
Corrosion Proof
Monitoring groundwater under potentially corrosive conditions, such as brackish water and seawater, requires a robust and durable datalogger.
The ceramic-shelled Cera-Diver is designed specifically for such environments. This highly reliable and compact Diver measures groundwater levels with a typical accuracy of ±0.05% full scale.
The Cera-Diver is equipped with a memory for 48,000 measurements per parameter.
