Description
Where there is a need to monitor groundwater levels and salt water intrusion, injected wastewater, or contamination from chemical discharges and landfill sites, the CTD-Diver with its 22 mm diameter rugged corrosion-proof ceramic (zirconium-oxide) housing is the instrument of choice.
The CTD-Diver is a submersible datalogger for long-term, uninterrupted, real-time water level monitoring using a pressure sensor when submerged at a fixed level under the water surface. The pressure sensor measures the equivalent hydrostatic pressure of the water above the sensor diaphragm to calculate the total water depth. The ceramic casing is suitable for brackish or saltwater applications as well as aggressive environments.
Connect the diver to a modem to transmit collected data directly from the field to your data centre.
Features
The CTD-Diver is an ideal choice for ground and surface water level applications. The water logger is equipped with a four-electrode conductivity sensor that measures electrical conductivity from 0 to 120 mS/cm. This type of measuring cell is relatively insensitive to sensor fouling, thus keeping maintenance to a minimum.
Compact size: diameter of 22mm and length of 135mm
Memory: 144,000 records of time stamp, pressure, temperature and conductivity (and 144,000 back-up)
30-Point Pressure Factory Calibration
Corrosion-proof ceramic pressure sensor
Various methods for measurement
Event based, averaging and pumping tests sample method to conserve memory
Special software is available for the Divers. Download via WeTransfer.
Measuring conductivity
A change in conductivity may be caused by for example changes in water flow, or increasing/decreasing pollution or salinization. The CTD-Diver measures the conductivity of a solution and can be programmed by the user to measure either the true conductivity or the specific conductivity at 25°C.
