The WET150 – a game-changing sensor for system integration
Delta-T Devices has been at the forefront of soil and substrate sensor technology for over three decades, with a range that includes the WET 2 – used extensively in horticulture worldwide for many years. With a strong heritage in developing instruments for scientific research, our sensors are built to high specifications and offer both excellent accuracy and premium build quality.
Through recent in-house design innovations the WET150 Sensor delivers this proven level of quality at a price point not previously thought possible. These technical breakthroughs mean that researchers, consultants and growers can now integrate a true research-grade multi parameter soil and substrate sensor into their systems at lower cost – making those systems even more effective, reliable and affordable.
Measurement of 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 accurately calculate pore water conductivity (ECp): the ion content of the water available to the plant. Patented sensor electronics produce research grade measurement accuracy with exceptional salinity and temperature stability – essential for critical control and irrigation decisions. When the WET150 is buried, temperature measurements (essential for compensating the EC measurements) are taken down in the root zone, ensuring highest accuracy.
When installed in grow bags, WET150s can provide the accurate data required to power sophisticated SDI-12 enabled automatic precision irrigation systems – cutting costs and waste whilst boosting produce yields and quality. The rugged watertight build of the WET150 also makes it ideal for use in field agriculture – sensors can be left buried for years without loss of performance. WET150 sensors can also be buried at different depths to enable monitoring of soil moisture, temperature and EC profiles.
