Product Feature

The Diver^® has become worldwide the standard for monitoring groundwater levels since the market introduction in 2001. The proven reliability of the total concept, meeting your data secure, together with the small dimensions are some of the reasons for its great success. More than 60,000 Divers have been used worldwide in all kind of projects, from research projects in Africa, through aquifer management projects in the Middle East, to big automation projects in Europe.

By using the input of the users, but also because of the development of new market segments, the Diver family is recently extended with three new Divers and a software package called Pocket-Diver. All Divers are supplied with a 3 years warranty!

New CTD Diver Information

Reliable in all conditions

Where there is a need to monitor not only groundwater levels but also saltwater intrusion, injected

wastewater, or contamination from chemical discharges and landfill sites, the ceramic-casing on the

CTD-Diver is the instrument of choice. In addition to the pressure and temperature sensor, the CTD-Diver

has a four-electrode conductivity sensor for reading conductivity

across an expanded measurement range

(0-120 mS/cm). There are two options for measuring conductivity: displaying measured conductivity or

specific conductivity at 25 °C.

The CTD-Diver accurately records up to 48.000 measurements of groundwater levels, temperature and

conductivity with corresponding date and time.

The one-eye communication makes this compatible

with the Diver-Suite.
