Equitensiometer

The Equitensiometer (Equilibrium tensiometer) is a device for maintenance-free measurement of soil matric potential (suction, water availability for the plants). This device is based on a patented new principle and has many advantages over the normal water-filled tensiometer.


Advantages

  • Wide measurement range from 0 to -1500 kPa (compared to water filled tensiometer 0 to -85 kPa)

  • Independent measurement of soil properties

  • High accuracy: + / -10 kPa or 10%

  • Long-term stability due to a patented manufacturing technique

  • Absolute maintenance-free even under frost conditions

  • Ease of use

  • Used worldwide for more than 10 years


Applications

The Equitensiometer is suitable for stationary long-term monitoring of matric potential in soil
