Multi-parameter sensors for looking at water level, temperature, or electrical conductivity can help track changes in solute movement, groundwater recharge, and surface water hydrology.  Get remote access to water level, temperature, or electrical conductivity data by combining the Decagon multi-parameter water level sensors with the Em50G Wireless Cellular Data Logger.

CTD-10 Sensor Electrical Conductivity Temperature Depth

Continuously monitor groundwater and surface water level changes, along with electrical conductivity and temperature.

ES-2 Electrical Conductivity Temperature

The ES-2 Electrical Conductivity Sensor is designed to measure the electrical conductivity of water in a pipe or tank.

PS-1 Irrigation Pressure Switch

Track irrigation events with the rest of your soil moisture data by recording when water is turned on and off.
