The Cera-Diver is available in four ranges for monitoring the following depths:

• 0 - 33 ft (0 - 10 m)
• 0 - 66 ft (0 - 20 m)
• 0 - 164 ft (0 - 50 m)
• 0 - 328 ft (0 - 100 m)

Measuring 3.54 inches (90mm) in length and 0.86 inches (22mm) in diameter, this highly reliable and compact Diver registers groundwater levels with an accuracy of 0.05% (Full Scale). It is equipped with a memory capable of storing 48,000 measurements per parameter. This is suffi cient enough to perform one measurement every ten minutes for an entire year.

In addition to internal data storage, the Cera-Driver can be connected to an external data logger, such as the Stevens DataLogic 3000, or data telemetry systems with the Diver-DCX SDI-12 output adapter, allowing the Diver to be used for realtime data monitoring applications.

Manual data download in the fi eld from a Diver’s internal storage can be done by utilizing the optional USB Interface Cable and connecting the diver directly to a desktop or laptop PC.
