Description

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). That's almost one measurement every ten minutes for an entire year. Connect the diver to a modem to transmit collected data directly from the field to your data centre.

Features

The Cera-Diver comes with a 22mm diameter ceramic casing and is suitable for use in brackish and salt water, or other aggressive environments. 

Corrosion-proof

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
