Tensiometer for soil moistureEffective, convincing and inexpensive version of a measuring instrument for soil moisture.RemarkA water saturated porous clay cell is connected to an exchangeable manometer by means of awater filled airtight acrylic glass tube for measuring underpressure. Water in soil is under influenceof certain bonding energies with a corresponding water tension. By contact of the water saturatedcell with soil the existing underpressure of the soil water is transferred to the manometer via claycell and water filliing.MechanismThe absorbing tension of soil waters which is displayed as underpressure on the manometer riseswhen the soil moisture decreases.Tensiometer versionsAll versions are equipped with a manometer 0-600 mbar/ hPa.
