The Cera-Diver is a robust and durable data logger, suitable for measuring and recording groundwater levels and temperatures in potentially corrosive conditions. Available variations in range: 33', 66', 164', and 330' (10m, 20m, 50m and 100m).

  • Corrosion proof
  • Easy installation in almost every well
  • Compact size: only 0.87inch in diameter
  • Innovative ceramic housing technology
  • Reliable and accurate data
  • 48,000 records of time stamp, pressure and temperature


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.

In addition to its rugged casing, the Cera-Diver’s memory capacity can store up to 48,000 measurements (date/time, pressure and temperature) - almost one measurement every ten minutes for an entire year.


This Diver comes with a 0.86 inch (22mm) diameter ceramic casing and is suitable for use in brackish and salt water, or other aggressive environments. 

  • Various measurement methods
  • 30-Point pressure factory calibration
  • Event based, averaging and pumping tests sample methods to conserve memory
  • Suitable for cost effective frequent, long-term measuring
