The Full Range Tensiometer by UGT covers the complete range of pressure heads relevant for plants, that can reach up to 1500 kPa depending on the model.

Unlike other systems used for this measuring range the Full Range Tensiometer doesn't determine the pressure head inidrectly as a derived variabel,  but via a direct pressure measurement. It reacts quickly to changes in pressure head. A pressure range of 1000 kPa is achieved in a few minutes. Even after drying out beyond the limits of the measuring range, the measurement is continued independently as soon as the moisture increases again. Refilling is not necessary. A further advantage compared to other measuring devices for the complete plant relevant pressure head range is the low energy consumption (20 mA in operational mode). This makes the Full Range Tensiometer is particularly suitable for remote measurement sites 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 longer distances.


The measurement is reliable also in difficult media. Saline sites, such as in aride areas, are not a problem as a result of the direct pressure measurement when correct calibrated.


The soil temperature is recorded as an additional parameter.
