Soil can be highly variable in space, requiring many measurements and frustrating amounts of your research dollars. Not to mention the extra cost and hassle of replacement sensors if you need long-term data. Make large sensor networks simpler, longer- lasting, and more affordable with the ultra- dependable TEROS 11 soil moisture and temperature sensor.
The TEROS 11 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% VWC accuracy, the TEROS 11 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. Plus, TEROS sensor repeatability can be checked with an accuracy verification standard. No other soil moisture sensor has this abilitv. Just slide the verification clip onto a sensor and plug it into a logger. If it reads within the right range, your sensor is good to go.
The TEROS 11 volumetric soil moisture sensor delivers the best volume of influence to sensor size on the market so you're less susceptible to soil variability errors. We've optimized the circuitry in this 9.4-cm sensor to deliver an incredible one-liter volume of influence (versus the 200 mL typical for most sensors).
