STELZNER® agricultural measurement systems

Measuring instruments for soil moisture and water monitoring, using sensors, tensiometers and data loggers

Bambach Premium plug-in tensiometer-GL

The special features of this design are the spacious, stable tube and the strong, long, cylindrical porous cell. In addition to its mechanical stability, a key advantage is the extended service life that results from the greater filling volume.


The shrunk protective tube with viewing window increases the tightness of the seal. Tensiometers usually protrude 8 to 10 cm from the ground to avoid the temperature influence of tubes protruding too far out of the ground. The total length should therefore be determined by the desired measuring depth. It is also possible to connect different thread types to implement irrigation controls with switching sensors etc.


Please, order the digital manometer separately.
