The WET Kit’s compact rugged WET-2 sensor is easily inserted into substrates, composts and most soils, and, in just 5 seconds, it measures three crucial variables that influence plant growth: water content, temperature and electrical conductivity (a strong indicator of nutrient levels). The WET Kit has crucial applications in precision horticulture and soil science research - and is unique in its ability to reliably measure pore water conductivity (ECp), the EC of the water that is available to the plant. The WET Kit includes a WET-2 Sensor, an HH2 instant readout meter, and a tough lightweight carry case.
