Accuracy made easy
Soil temperature is a critical parameter for understanding the whole energy balance. It’s often used in surface energy balance models and predictions. If you need a simple, accurate way to make soil temperature measurements in the soil profile and monitor those measurements remotely, the TEROS 06 is your go-to, all-in-one solution.
More accurate than other sensors
The research-grade TEROS 06 accurately measures and records soil temperature over time at six depths exceeding WMO recommendations. It contains digital sensors at -5 cm, -10 cm, -20 cm, -30 cm, -50 cm, -100 cm. And, unlike other profile probes on the market, every TEROS 06 sensor is individually calibrated for the highest possible accuracy (±0.1°C).
TEROS 06 has a small diameter of 20 mm to minimize soil disturbance, plus it was specifically engineered to eliminate heat transfer. The fiberglass-reinforced plastic body has a very low thermal conductivity, so there is no temperature carryover between profile layers. Stainless steel rings ensure excellent heat conductance from the soil to the sensor, so you know you’re only measuring soil temperature at a precise location.
Insanely simple setup
We designed the TEROS 06 to be incredibly easy to install. Just auger a hole with the specially-made auger, and insert the probe. Then, plug the sensor into your ZL6 logger and start collecting data. It’s that easy. The logger auto-recognizes the TEROS 06 for simplified setup and configuration. The TEROS 06 also works with non-METER loggers.
Reliable data on the go
Easy and reliable data collection, maintenance, analysis, and sharing are all part of the TEROS experience. Combine the TEROS 06 and ZL6 logger with ZENTRA Cloud, where all data are connected and delivered anywhere in the world in near-real time. All you have to do is sit back and let the data flow.
Get more for less
Backed by 20 years of precision engineering and painstaking attention to detail, the ultra-robust TEROS 06 is a high-quality, research-grade temperature profile probe that delivers the accurate soil temperature data you need for better models and predictions—with far less hassle.
