HYDRO 2000 with plug connection

Determining the volumetric water content in the soil

The HYDRO 2000 is an inexpensive measuring device for professional use. It determines the volumetric water content in soil. The SMT 50 sensor works according to the FDR (frequency domain reflectory) principle. It delivers precise results in the relevant measuring range between 0 and 50 % water content by volume, with only slight influences from salinity and soil type. The cable and housing for the sensor are waterproof.

In addition to measuring soil moisture, the HYDRO 2000 can also measure the temperature of the soil. Thanks to its compact and robust design, this measuring device is maintenance-free and suitable for continuous operations.

The HYDRO 2000 can be optionally deliverd with a cable connection for connecting further volume sensors and to handle additional measuring tasks.

Bambach-BLUMATplug-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
