It is usually recommended to saturate vacuum tensiometer with deaired water to slow down the growth of the air cavity in the tensiometer tube and hence to prolong suction measurement. However, it is difficult to refill the instruments with ...

After testing, remove the cap from the tensiometer and stand the tensiometer upright in a pail of water and allow for the cup to resaturate overnight. Fill tensiometer with deaerated water, which can be prepared by boiling and cooling the water.

When the tensiometer is placed in the soil, the water within the instrument equilibrates with the soil water through pores in the ceramic tip. As the soil near the ceramic cup dries and the matric potential increases, water is drawn from the ...
