TEROS 10 Soil Moisture Sensor

If you think big, you'll love this nearly bulletproof sensor.

Large sensor networks have always made a substantial hole in the research budget, especially because many soil moisture sensors have issues with reliability. Not only that, traditional sensors force researchers to choose between accuracy and affordability. Not anymore. The new, ultra-robust TEROS 10 soil moisture sensor delivers scientific accuracy and reliability at a price that makes large sensor networks economically practical.

Everything you need. Nothing you don't.

The TEROS 10 is a ruggedized version of our basic, no-frills soil moisture sensor. Its 70-MHz frequency minimizes salinity and textural effects, making it accurate in most soil or soilless media. With a tough, epoxy body the TEROS 10 is designed to withstand some of the harshest field conditions, which means problem-free measurements over the longevity of your research. The TEROS 10 sensor lets you characterize your site with sensors at multiple depths and locations, even on a tight budget.

Long-lasting precision that's short on cost

The TEROS 10 is built to last longer in the field under harsh conditions. No more worrying about surprise data gaps due to failed sensors. It's one of our toughest soil moisture sensors, and its body withstands difficult environments and water intrusion for up to 10 years. Ideal for large sensing networks, it is sensitive to small VWC changes across the entire range of soil and substrate water content, and can be installed in anything from dry desert soils to very wet peat. Not only that, the TEROS 10 has very low power consumption and a high resolution.

Banish data uncertainty

More than just a sensor, the new TEROS 10 soil moisture sensor treats the whole accuracy problem, rather than just one part of it, by eliminating common problems that cause uncertainty in the data-like air gaps, or preferential flow. How? The TEROS 10 is compatible with the TEROS Borehole Installation Tool, which mistake-proofs installation. Because of its mechanical advantage, the tool delivers consistent, flawless installation into any soil type (even hard clay) while minimizing site disturbance. Sensors are installed straight in and perpendicular with uniform pressure then gently released to prevent air gaps and preferential flow. This means the TEROS 10 is able to deliver more accuracy with less uncertainty than similar sensors on the market.

Easy integration. Easy installation. Easy everything.

With improved high-quality, sharpened and securely fastened stainless steel needles, the TEROS 10 glides into any soil. Then, simply plug it into any METER data logger and start collecting data. It's that easy. No wiring. No programming. And the analog signal from the TEROS 10 sensor ensures that it can easily be integrated into a wide variety of non-METER systems.

Get your data faster

Easy and reliable data collection is part of the TEROS 10 experience. Combine the TEROS 10 with the new EM60G, where all data is connected and delivered through the cloud. Collect data in near real time, from the comfort of your office. So all you have to do is sit back and let the data flow.

Monitor more, spend less

If you are planning a large sensor network and want more measurements for less investment, without compromising accuracy or reliability, then plan to use the easy, affordable and ruggedized TEROS 10 soil moisture sensor.
