The TEROS 12 soil moisture sensor uses a completely new calibration procedure that maximizes accuracy and minimizes sensor-to-sensor variability while keeping the cost reasonable. So you can be confident that every sensor you install is going to read exactly like the next one. Unlike other sensors on the market which spec an unverifiable ±1.0% accuracy, the TEROS 12 was rigorously tested by our soil physicists across a challenging range of soil types and EC levels so you can be confident in the accuracy of your data.

The TEROS 21 soil suction sensor is incredibly easy to use, and it requires no maintenance. In fact, the TEROS 21 provides an even more accurate moisture picture than measuring water content alone. A water content sensor only shows the percentage of water in the soil, but add a TEROS 21, and you'll be able to monitor the strength and durability of your geomaterials. Check it out here.
