Půdní tenzometr TMS11A
TMS11A - Soil tensiometers

Soil tensiometer designed to measure the suction pressure in the soil

  • Sensor with ceramic head with a diameter of 25 mm and a length of 200 to 1000 mm
  • Filling the soil tensiometer at the measuring point with the help of led-out capillaries
  • Wide measuring range from negative pressure -65 kPa to flooding 3 m level
  • Evaluation and correction of measured pressures in the TM4 module
