Soil Tensiometer TEN120

Irrigation Meter dengan Panjang 120cm

====

* Soil tension meter is an instrument for monitoring soil moisture and determining irrigation time in agricultural production.

* Direct determination of soil water potential (soil moisture), all kinds of soil general, no correction.

* Easy to install, easy to manage, user can determine irrigation time according to dial pointer display

* Instrument composition: tensiometer tube, needle negative pressure meter

* The soil hygrometer consists of a collector, a vacuum gauge and a clay pipe. The upper end of the collecting pipe is an injection nozzle with a rubber plug. A side interface is connected to the vacuum meter, and the lower end is connected to the clay head through the plastic pipe.

Technical parameters:

Measurement range: 1bar (1bar = 100kpa)

Length: 47.2 inches (120 cm).

Principle:

Soil water potential meter is made up of pressure gauge, acrylic tube and ceramic probe.

After filling the acrylic tube with water, the ceramic probe is wetted and can prevent the external air from entering the ceramic probe.

When there is a pressure difference between the measured soil water potential and the tensiometer, the water in the tensiometer seeps into the measured soil until it reaches the equilibrium state, and the value shown by the pressure gauge is the soil water potential of the measured soil.
