Stelzner Tensiometer Classic Tensiometer Soil moisture

Tensiometers are used for continuous measurement of the soil moisture on the basis of the suction power. The TENSIOMETER measures the suction voltage from 0 to about 600 mbar. It transports the tonzelle of the TENSIOMETERS in a dry environment by their intensity of the capillary water from the inside to the outside, so that in closed pipe, a vacuum is produced. This vacuum is a measure of moisture. The suction power is the force with which the water is held in the ground or is available. This force must provide the plant roots for water. An intensive substrate contact is a prerequisite for a fast tensiometers response and for the measurement of typical values of certain soil and substrate types.
