    Delta-T - Model EQ3 - Equitensiometer

    The EQ3 uses class leading ThetaProbe technology to avoid the many problems of water-filled tensiometers. It measures water potential (matric potential) in the range 0 to -1000 kPa and provides an accurate loggable output. It is particularly well suited for use in dry soils.

    TensioMark - Matric Potential Sensor

    The TensioMark measures the soil water potential or matric potential. The soil matric potential is the pressure it takes to pull water out of the soil and is an indicator of stress to plants and crops, can be used to determine soil water fluxes and available water held in the soil. Water equilibrates with the ceramic tip portion of the sensor ...

  • Tensiometers

    These modernized tensiometers, built by German company UMS, are THE most accurate way to measure soil matric potential. Thanks to precision engineering, meticulous construction, and fanatical attention to detail, they have terrific accuracy and a range that (with a skilled operator) can extend beyond -200 kPa.

  • 229-L Water Matric Potential Sensor

    The 229-L Water Matric Potential Sensor measures soil water potential from 0.1 to 10 bars. The sensor consists of a heating element and thermocouple emplaced in epoxy in a hypodermic needle, which is encased in a porous ceramic matrix. To calculate soil water matric potential, a Current Excitation Module applies a 50 mA current to the 229's ...

  • Irrigation Monitoring System

    Know When to Turn it On: Most irrigation systems rely exclusively on soil moisture sensors. Soil moisture sensors can't tell you how much of the water that's present is actually available to plants. This system uses an MPS-1 matric potential sensor to measure plant available water so you know when to turn the water ON. Know When to Turn it Off: ...
