Meter Stainless Steel Teros 22 Soil Water Potential Sensor

The TEROS 22 water potential sensor is incredibly easy to use. It requires no maintenance, and it’s accurate enough for most applications. In fact, the TEROS 22 provides an even more accurate soil moisture picture than measuring water content alone. Plus, unlike water content, matric potential isn’t dependent on soil type, so you can compare moisture between different sites. Just like the TEROS 21, the TEROS 22 is surprisingly affordable and measures all the way from near saturation to air dry (0 to −100,000 kPa) making them both true full range water potential sensors.
