The CTD-Diver is impervious to the most aggressive substances found in water environments. Its ceramic casing resists when even the strongest metals yield.

CTD-Diver is a highly reliable, compact probe for the simultaneous measuring of groundwater level, temperature, and conductivity. These parameters are measured at time intervals pre-determined by the user. The measured values are stored in the probe's non-volatile internal memory and can be read out at any given time.

In addition to internal data storage, the CTD-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 real-time data monitoring applications.

Manual data download in the field 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.
