Our latest research-grade multi-parameter soil sensor
Measures moisture, temperature and EC
Accurate monitoring of growing conditions
Measures directly in the rootzone
Digital SDI-12 for easy system integration
Detachable and extendable cable system
The digital multi-parameter WET150 soil sensor represents the culmination of forty years research and development at Delta-T Devices.
Benefiting from a number of important design innovations, the WET150 delivers research-grade accuracy and build quality at a price point not previously thought possible. This means growers can now integrate a true research-grade multi-parameter sensor into their precision irrigation and environmental control systems at lower cost – making those systems even more effective, reliable and affordable.
Measures three crucial growing media variables
When buried in soil or substrate the WET150 Sensor simultaneously measures three crucial variables that influence plant growth: moisture content, temperature, and electrical conductivity (EC) – a strong indicator of the general nutrient level.
An important feature of the WET150 is its ability to reliably calculate pore water conductivity (ECp), which is the ion content of the water available to the plant.
The WET150s patented sensor electronics produce research grade measurement accuracy with exceptional salinity and temperature stability – essential for critical control and irrigation decisions. When the sensor is buried, temperature measurement (essential for compensating the EC measurement – for optimum accuracy) is measured directly in the root zone.
Applications
Horticulture and agriculture – The WET150 Sensor is available with a comprehensive set of soil and substrate calibrations and provides a simple, effective, rugged solution to checking the uniformity of growing conditions for many types of growing media.
Plants that are grown in artificial substrates routinely receive their nutrients in irrigation water – in the process known as “fertigation”. Nutrient levels can be controlled by monitoring the water content and conductivity (EC) and adjusting the injection of liquid fertiliser into the irrigation water. The WET150 Sensor excels in accurately measuring this crucial information.
Precision irrigation – The WET150 sensor is ideal for precision irrigation applications and its compact design allows it to be easily installed in grow bags. The WET150’s accurate sensor data can be used to optimise irrigation scheduling, or drive an SDI-12 enabled automatic irrigation system.
Soil salinity monitoring – When irrigation water is recycled or abstracted from rivers with high levels of dissolved salts, over time there can be a buildup of soil salinity. Soil salinisation will eventually reduce crop yields. The WET150 Sensor is a powerful tool for sampling soil salinity, ensuring that growers and farmers have the essential information they need to take remedial action as quickly as possible.
System integration – The WET150’s accurate and stable three parameter measurement, simple SDI-12 output and low power makes it the ideal sensor for system integrators. Industrial rated, UV resistant cable fitted with a waterproof IP68 connector allows the sensor to be buried indefinitely, whilst still permitting easy cable exchange or extension if necessary.
Soil science research – The WET150 is easily integrated into SDI-12 systems and delivers research-grade accuracy and reliability for researchers monitoring soil or substrate conditions. Typical areas of use include irrigation research, crop trials, phenotyping, hydrology, soil water profiling, and forestry.
