TEROS 10
Simple Soil Water Content Sensor

Everything you need. Nothing you don’t.

The TEROS 10 soil water content sensor 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. In fact, we’re so confident about the long life of our TEROS sensor line, we’ve increased our standard warranty from one to three years.

Long-lasting precision that’s short on cost

The TEROS 10 sensor lets you characterize your site with sensors at multiple depths and locations, even on a tight budget. It’s 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 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.

Simple to use. No need for calibration in most soil types. 

You don’t have to worry about the complexity of calibration. We’ve already calibrated the TEROS sensor to be extremely accurate in 95% of all soil types right out of the box. If it’s an unusual soil, or if you need even better accuracy, then a soil-specific calibration might be the way to go (see performance comparison) 

Plus, the analog signal from the TEROS 10 sensor ensures that it can be easily integrated into a wide variety of non-METER systems. Or, simply plug the TEROS 10 into the ZL6 data logger, and start collecting data. It’s that easy. All data are connected and delivered through the cloud. See data in near-real time from the comfort of your office, or anywhere in the world.

Faster, better installation

More than just a sensor, the new TEROS 10 eliminates common problems that cause uncertainty in the data—things like air gaps and 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 no side-to-side movement, then gently released to prevent air gaps and preferential flow. This means the TEROS 10 delivers more accuracy with less uncertainty than similar sensors on the market. And, with improved high-quality, sharpened, and securely fastened stainless steel needles, the TEROS 10 glides into any soil.
