Full Range Tensiometer 2.0

Measurements up to the permanent wilting point pF 4.2

With the Full Range Tensiometer 2.0, UGT GmbH offers a further development of the maintenance-free, innovative polymer-filled tensiometer with integrated temperature measurement. The new polymer composition and improved ceramic enables an even shorter reaction time with increased maesuring accuracy.

Measurements beyond borders.

Tensiometers are widely used instruments for a detailed investigation of the water balance of an ecosystem. Conventional water filled tensiometers are able to measure up to approx. – 90kPa. This limited measuring range greatly limits research and monitoring tasks, especially in areas with dry soils, which will increase in the context of climate change. The worldwide new and patented Full Range Tensiometer 2.0 is a polymer tensiometer which covers the entire pressure head range relevant for plants up to 1500 kPa (pF 4.2). It is perfectly adapted to the requirements of also dry soils. Saline locations, such as in arid areas, are no problem due to the direct pressure measurement and correct calibration.

Ready for use in the field and in the laboratory.

Both large lysimeter stations and complex measuring sites as well as small lysimeters: Ready-to-go lysimeters, laboratory lysimeters and the EcoLab can be equipped with this high-resolution and extended polymer-filled tensiometer measuring technology and thus extend the measuring range. The new ku-pF 4.2 SP combines the precision of water- and polymer-filled tensiometers. By combining the latest RFID and polymer tensiometer technology, we enable non-contact, direct and undisturbed measurements up to the permanent wilting point pF 4.2 in soil cores for the determination of complete pF – and hydraulic conductivity curves.

Maintenance-free in long-term measurements even under extreme conditions.

Climate researchers predict an increase in extreme weather events, i.e. the shift from very dry to humid soils will increase. The Full Range Tensiometer 2.0 continues the measurement automatically after drying out as soon as the soil moisture increases again. No refilling is necessary anymore. The Full Range Tensiometer 2.0 is robust in its construction, maintenance-free and designed for long-term use. Due to the integrated temperature sensor you have everything at a glance. A further advantage is the low energy consumption (20 mA current in measuring mode). This makes the Full Range Tensiometer 2.0 particularly suitable for locations where regular maintenance and a reliable power supply are not guaranteed.
