ST series
Portable Soil Irromerter Tensiometer
Introduction
Soil Irrometer tensiometer is made up of pressure gauge, acrylic tube and ceramic probe,
after the acrylic tube filled with water, ceramic probe gets wet and it can prevent outside air
into the ceramic probe. When there is pressure difference between measured soil water potential
and tensiometer, the water in tensiometer will infiltrate into the measured soil until the balance reached.
So at that moment, the value shown on the pressure gauge is the measured soil water potential.
Technical parameters
Length can be made as customized. (Standard length is the length of transparent polycarbonate tube
in the middle of tension meter tube);
Testing range: 0-1 Bar (1 Bar = 100 Kpa)
