Local approach and Made in France: manufacturing and assembly in Nancy, in the Grand-Est region of France, where WETRUF is based.


The pF Tracer One+ is a tool for measuring and reading soil water potential (pF) and soil temperature exclusively by connecting to the Duo pF and temperature sensor, the single gypsum sensor, or the single temperature sensor. Developed by WETRUF, it is the result of research conducted at INRAE.
The monitoring of the pF allows to adapt the water supply in an optimal way in order to guarantee a good productivity, even in periods of drought. To find out more, see Our concept, our innovation.
Temperature monitoring allows us to understand how variations in soil temperature impact truffle production and how they relate to variations in pF. To find out more, read our article on soil temperature.

Setting up the pF Tracer One+ is extremely quick and easy: simply connect it to a dedicated probe previously installed in the soil, and take measurements instantly by pressing and holding the read button. The portability of the pF Tracer One+ reader means that measurements can be taken regularly on a network of installed sensors, making it an indispensable tool for truffle growers in terms of watering management.
