Cera-Diver

The Cera-Diver is a rugged, corrosion proof groundwater datalogger.

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.

The Cera-Diver has the following sample methods: fixed length intervals, event-dependent, averaging, and pumping tests.

The Cera-Diver is available in the following pressure ranges: 10 m, 20 m, 50 m and 100 m.
