CTD-Diver - Model 50m, 0-120mS/cm -Measuring and Recording Groundwater Level/ Temperature/Conductivity
CTD-Diver for measuring and recording groundwater level/ temperature/conductivity. Memory for 48000 measurements. Conductivity 0-120 mS/cm, compensated temperature 0 till +50 °C. Measuring range 50 m. Accuracy EC 1% of the measured value. Housing ZrO2. Warranty 1 year.
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 CTD-Diver can be read out in situ or combined with telemetry.
