STELZNER® agricultural measurement systems

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

Surface tensiometer

Surface tensiometers can be used for measuring the moisture on irrigation fleeces, on substrate surfaces, within the substrate, as well as on other technical fleeces. Together with a switch sensor or E-sensor, they are used for irrigation control in mat irrigation systems – with either drip or flood systems – or in thin-layer crops with drip systems. More frequent refilling is required at suction pressures above approx. 300 hPa.


Height approx. 65 mm, Diameter of clay foot approx. 70 mm, Configuration also with T-piece 45° with two GL14s.

Please, order the digital manometer separately.

Bambach-BLUMAT plug-in tensiometer

A tensiometer is used to measure suction tension. The porous cell of the tensiometer uses capillary action to transport water outwards into the drier soil. A negative pressure is then created within the closed pipe. This negative... ...more Topseller
