Tensiometer Pronova

The Tensiometer measures the suction voltage in the soil that is important for the plant and does not have to be calibrated as a measuring instrument.
Suction tension is the force by which the water is held in the ground. This force must yield the plant roots in order to absorb water. The reason for this is the soil-specific fine pores and capillaries.
The special feature of this design is the large-volume, stable pipe and the strong, long and cylindrical tone cell. In addition to the mechanical stability, a main advantage is the extended service life due to the larger filling volume. Through the shrink-fit protective tubing with sight window, the leak-proof is increased. Tensiometers usually protrude 8-10cm out of the ground to avoid the effect of the temperature from pipes sticking out of the ground too long. The total length is therefore determined by the desired measuring depth.

Digital manometer:
The digital pressure gauge consists of a piezoresistive pressure sensor and a battery-powered display electronics. The device has to be switched on at the touch of a button for use.
