MPS-2 Dielectric Water Potential

Rain Bird® ClimateMinder™ System Sensors

The MPS-2 Maintenance-Free Water Potential and Temperature Sensor measures a wide range of soil water potentials (-10 to -500 kPa) without user maintenance and factory calibration.

This sensor is best for:

  • Deficit irrigation monitoring and control.
  • Water potential monitoring in the vadose zone.
  • Crop stress.
  • Waste water drainage studies.
  • Plant water availability.

Technical Specifications:

  • ACCURACY         
    • Soil Water Potential: ± 25% of reading from -10 kPa to -100 kPa, see user manual for more details on accuracy
    • Soil Temperature: ± 1°C
  • RESOLUTION     
    • Soil Water Potential: 0.1 kPa
    • Soil Temperature: 0.1°C
  • RANGE
    • Soil Water Potential: -10 to -500 kPa (pF 2.01 to pF 3.71)
    • Soil Temperature: -40° to 60°C*
  • SENSOR TYPE: Frequency domain with calibrated ceramic discs, thermistor
  • OPERATING ENVIRONMENT: -40° to 60°C
