Van Essen CTD-Diver Sensor
Spec Sheet

Diver Office Software (Van Essen)


DIVER SENSORS

Where there is a need to monitor not only groundwater levels but also saltwater intrusion, injected wastewater, or migration of contaminants or mine tailings, the CTD-Diver is the instrument of choice. In addition to the pressure and temperature sensor, the CTD-Diver has a four-electrode ceramic sensor for accurately reading conductivity up to 120 mS/cm. There are two options for measuring conductivity: displaying measured conductivity or specific conductivity at 25°C.

With an improved compact ceramic housing, CTD-Diver is ideal for small diameter wells. The expanded nonvolatile memory will store up to 48000 measurements of water level, temperature, and conductivity with date and time. CTD-Diver is integrated with field acquisition accessories and desktop software.

DXT WIRELESS COMMUNICATION OPTIONS

If access to the well is limited by for example fences or water the Diver-DXT can be installed to wirelessly collect Diver data up to a distance of 500 meter.

The Diver-DXT is a battery powered radio device to acquire data and adjust Diver settings wirelessly from the Diver to the Diver-Gate. A built-in barometric datalogger is used to convert pressure data into accurate groundwater levels.

Features

  • Connects directly to Diver dataloggers via an adjustable, detachable cable
  • Contains a built-in barometric pressure and temperature datalogger (model AS401 only) for automatic barometric compensation
  • Durable, robust and water resistant housing

Benefits

  • Extra long battery life perfect for long-term monitoring
  • Suitable for various different installation types: above ground, below ground (street pot), within synthetic protective cover
  • Easy to install and adaptable to most monitoring wells
  • Provides wireless long-range communication for remote data collection
