text: The MPS-6 is a matric water potential sensor that provides long term, maintenance-free soil water potential and temperature readings at any depth without sensitivity to salts. The range of the MPS-6 goes from field capacity to air dry. Lab and field tests indicate that it can make accurate measurements at water potentials at least as dry as permanent wilting point.
  Excellent Range - The MPS-6 has sensitivity from -9 kPa all the way to air dry (-100,000 kPa).
