The Portable Soil Irrometer Tensiometer is a reliable instrument for measuring soil water potential in agricultural, horticultural, and environmental applications. Built with a pressure gauge, durable acrylic tube, and ceramic probe, it provides accurate readings of soil moisture conditions to support effective irrigation planning and soil management.
When the ceramic probe is inserted into the soil and filled with water, it measures the tension between soil water and the tensiometer. The value shown on the gauge indicates the soil water potential at equilibrium.
Measures soil water potential with high accuracy
Sturdy construction with pressure gauge, acrylic tube, and ceramic probe
Prevents outside air infiltration for reliable measurements
Available in multiple lengths to suit different soil depths
Lightweight, portable, and easy to use in the field
Ideal for precision agriculture, irrigation management, and soil research
