HydraProbe II Soil Moisture sensor

The Stevens HydraProbe is the most scientifically researched soil sensor available and is offered by PP Systems as an all-in-one in-situ sensor that can measure both soil moisture and soil temperature. This rugged probe has completely sealed electronics making it fully immersible in water, and three strong, non-bending and non-corrosive stainless steel tines. For best results, the 3 prongs should be pushed all the way into the ground until the white body of the sensor is at minimum flush with the soil surface.
