It can be deployed on all irrigation systems, such as:

  • Centre pivots
  • Micro irrigation
  • Drip irrigation
  • Flood / surface irrigation
  • It is also particularly well suited for crops like pastures or sugarcane where a sub-surface probe is preferred.

It comes standard with:

  • 5 sensors (up to 10)
  • Probe diameter is 38mm.
  • Probe lengths options are from 100 mm to 1,500 mm
  • SDI-12 communication interface.
