What will you choose?
With all of the different soil moisture sensor options available today, it can be difficult to know which one to choose.
At METER, we believe that choosing the right sensor should be simple. Why make compromises when you don’t have to?
This is why we developed the TEROS 12 soil moisture sensor. The sensor combines all the features you need. So you never have to make a compromise between performance, reliability, and price.
The all new TEROS 12 sensors use capacitance sensing technology to deliver an excellent price to performance ratio in a device that is easy to use.
Our new calibration procedure maximizes accuracy and minimizes sensor-to-sensor variability. So you can count on the same level of performance from every sensor.
Also, TEROS 12 sensors have soil temperature measurement included with every sensor. So, you have all the information for temperature corrections, or if you just need temperature to understand biophysical processes in the soil.
And now, you can connect TEROS 12 sensors to the ZENTRA ZL for simple, plug-and-play data logging and cloud-based data storage and management. Because what good are data if they aren’t accessible when you need them?
An ideal solution.
TEROS 12 soil moisture sensors combine accuracy, affordability, simplicity, and reliable functionality – all connected and delivered through the cloud – making them the ideal solution for soil moisture measurement.
