WET-2 Sensor - (Contenido de Agua, EC y Temperatura) 

  • Measures Water content, EC and Temperature
  • Measures directly within the root zone
  • A vital tool for precision horticulture

 The WET Sensor has crucial applications in precision horticulture and soil science research and is usable in both soils and growing substrates. It is exceptional in its ability to measure pore water conductivity (ECp), the EC of the water that is available to the plant.


Fertigation and hydroponics
Where plants are grown in artificial substrates using hydroponic or fertigation systems, nutrients are routinely supplied in irrigation water. Nutrient levels are controlled by monitoring the water content and conductivity (EC) and adjusting the injection of liquid fertiliser into the irrigation water. The Delta-T Devices WET Sensor excels in monitoring this crucial information.


Container-grown shrubs and trees
Nutrients are sometimes provided by fertigation but are often provided by Controlled Release Fertilisers (CRF). The rate at which these are taken up depends on several factors, including the weather conditions and irrigation regime.

The Delta-T Devices WET Sensor can be used to measure the EC within the growing media and so take much of the guesswork out of this process.


Soil salinity
If the irrigation water is recycled or abstracted from rivers and aquifers with high levels of dissolved salts, over time there can be a build up of soil salinity. Soil salinisation will eventually reduce crop yields. The WET Sensor is fast and efficient for sampling soil salinity, ensuring that farmers have the essential information they need to take remedial action as quickly as possible.


WET Kit
WET Sensors are normally ordered as a complete kit that includes a WET Sensor, an HH2 Moisture Meter and a handy carry case. There are three types of Kit - each with a different set of substrate calibrations. Please download our Soil Moisture Measurement catalogue for further details.

 

Readout and data logging
For portable applications, readout and data storage are handled by the HH2 Moisture Meter. Alternatively, the WET Sensor can be connected to the GP1 Data Logger or GP2 Data Logger and Controller, making it possible to monitor growing conditions over a period of hours, days or longer. The smart relay capability in these data loggers allows them to control water content in response to EC or temperature.


Soil and horticultural substrate calibrations  
The WET Sensor is supplied with calibrations for generid mineral, organic, sand and clay soils. Special substrate calibrations can be ordered as a set for a variety of horticultural substates which are factory installed at Delta-T Devices.
