Our Full Range Tensiometer FRT 15D not only measures the water tension and the soil temperature, but also the soil moisture. You can also use the tensiometer stationary in the field for long periods of time. The low energy consumption in the measuring mode and the hardly necessary maintenance make the polymer tensiometer a perfect companion for your research.

What can the Full Range Tensiometer do?

The Full Range Tensiometer covers the entire water tension range relevant for plants, up to 1500 kPa depending on the design. In contrast to other systems for this measuring range, it does not determine the water tension indirectly as a derived variable but via a direct pressure measurement. It reacts quickly to changes in the suction tension. A pressure range of 1000 kPa is passed through in a few minutes. Even after drying out over the measuring range, the measurement is continued independently as soon as the humidity increases again. No filling is necessary.

Another advantage compared to other measuring instruments for the complete plant-relevant suction range is the low energy consumption (20 mA current in measuring mode). This makes the Full Range Tensiometer particularly suitable for remote measuring locations where regular maintenance and reliable power supply are not guaranteed. Data transmission via RS485 allows communication even in environments with increased risk of electromagnetic interference and over longer distances.

Variant FRT 15D without soil moisture

If you are already measuring the soil moisture with another sensor, we also offer this tensiometer as a variant without this parameter.
