Soil moisture sensor WET150

temperaturedigital

• Our latest research-grade soil sensor • Measures moisture, temperature and EC • Digital SDI-12 for easy system integration • Rugged, buriable and low power • Accurate monitoring of growing conditions • Detachable and extendable cable system • 5 year warranty The digital multi-parameter WET150 soil sensor represents the culmination of forty years research and development at Delta-T Devices. Through a number of key design innovations it delivers research-grade accuracy and build quality at a price point not previously thought possible. It is the ideal sensor for research of soil conditions – and for integration into SDI-12 environmental and horticultural measurement/control systems. A digital SDI-12 sensor that measures three crucial 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. A key strength 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 – to obtain optimum accuracy) is taken directly from the root zone.
