COMBI 5000 for mobile soil moisture measurement

The hand-held meter COMBI 5000 can be used as a successor to the previous measuring system MST 3000. After factory programming, only the soil moisture and temperature measuring function is activated. The newly developed multi-probe is also used in this case only for a selective determination of volumetric soil moisture and soil temperature.

The measuring principle is based on FDR (Frequent Domain Reflectometry) technology and enables an objective measurement, only negligibly influenced by other chemical soil parameters such as pH and salinity. Easy handling, immediate and direct display of the measured values in % vol. of moisture and C° of temperature, topped with applicability in all soils and horticultural substrates are the outstanding features of the newly developed measuring system.

Areas of application:

  • growing media, such as peat substrates, coconut fiber, bark substrates, mineral substrates (such as rock wool), etc.
  • directly in containers, pots and grow bags. Ideal for indoor greenery
  • outdoors in mineral soils, for example for irrigation control of agricultural areas, viticulture and hop cultivation
  • open ground vegetables, asparagus, strawberries and berry fruits
  • experimental procedures, such as drought stress experiments
