Teros 21 GEN 1

The TEROS 21 Soil Water Potential Sensor measures a wide range of soil water potentials without user maintenance. This dielectric water potential sensor can be packed into a hole, plugged into a data logger, and left to log water potential data.

Device Information

While the TEROS 21 sensor does not have the accuracy of tensiometers, its extended range makes this sensor ideal for measuring the water potential in natural systems or other drier systems where cavitation of tensiometers is a concern. The added temperature measurements can be used to determine approximate soil water potential in frozen soils.
