Decagon GS3 Soil Moisture, Temperature and Conductivity Sensor Ruggidised
GS3 Ruggedized Soil Moisture, Temperature and EC
The GS3 soil moisture, temperature, and EC sensor is built with an epoxy body and stainless steel needles. The internal circuitry is the same cutting edge design that you'll find in other Decagon soil moisture sensors, but the form factor has been optimized for use in soilless substrates or harsh environments, giving it a wider range of EC measurement and an increased temperature range. Not only do the steel needles improve sensor contact, but they also improve the sensor's ability to measure EC in porous substrates such as peat or perlite.
Accuracy at a Fraction of the Cost
The GS3 measures water content, temperature, and EC independently. Its 70 MHz frequency minimizes salinity and textural effects, making it accurate in most soil or soilless media. Stainless steel needles have an extended surface area to optimize EC measurements, while minimizing substrate disturbance during insertion. Temperature is measured with an onboard thermistor, and electrical conductivity is measured using a stainless steel electrode array.
