0°C to 60°C Stainless Steel Soil Tensiometer, Color : Grey

A Soil Tensiometer is a scientific instrument used to measure soil water tension (matric potential), which indicates how strongly water is held in the soil and how easily it is available to plant roots.
It operates on the tension (vacuum) principle, where a porous ceramic cup filled with water is inserted into the soil. As the soil dries, water is drawn from the cup, creating a measurable vacuum that correlates directly with soil moisture tension.

This measurement helps in determining the optimal irrigation timing, avoiding both under- and over-watering. Soil tensiometers are widely used in agriculture, horticulture, irrigation research, and soil science laboratories to monitor soil moisture dynamics.
