TEROS 54 Sonda de Perfil de Humedad del Suelo
You need accurate soil moisture measurements from easily installed sensors without extensive excavation. Most profile probes require you to choose between ease of installation and removal, sensor accuracy, measurement volume, and durability. At METER, we weren’t willing to create a soil moisture profile probe unless it could meet all of these requirements. That’s why we made the TEROS 54.
There’s the hard way, and then there’s the right way
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.
Get in. Get out. Get data.
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.
