We designed the TEROS 54 profile probe to make every step of your measurement process easier—without sacrificing accuracy or durability. Soil water content and temperature sensors are positioned at 15, 30, 45, and 60 cm depths, providing root zone measurements without requiring soil pits or cumbersome sensor retrieval at lower depths. You get the convenience of profile measurements combined with the research-grade accuracy you’ve come to expect from METER.
Avoid the cost, hassle, and time of large drilling equipment and pilot tubes. TEROS 54 installation only requires a simple 2 cm borehole for the robust quad-fin profile sensor to then be hammered into the soil. This creates better sensor/soil contact for more accurate readings. Removing the TEROS 54 is made simple with the dedicated extraction tool, making this sensor ideal for annual crops that require sensors to be installed and removed multiple times throughout the year.

See the bigger soil moisture picture
Other cylindrical profile probes have a minimal measurement volume, only allowing you to see what is happening in a small volume of soil. The quad-fin design of the TEROS 54 creates a large measurement volume than the typical soil moisture profile probe, providing a more holistic view of soil moisture status. More sensors per data logger combined with more soil measured with each probe means you can build a larger data pool with fewer resources. And with ZENTRA Cloud, you can see all your data remotely in real time from the comfort of your own desk.
Complete confidence in your data
Since 2001 METER has been dedicated to producing highly accurate, easy-to-use soil moisture sensors, but we haven’t offered a profile probe—until now. We made the bold decision that our profile probe had to compare to the quality and accuracy standards that environmental researchers have come to rely on from METER. With the TEROS 54, you can measure confidently, knowing your sensors are designed and constructed by scientists who understand the challenges you face and the importance of getting it right.
