Tensior T8 - Eijkelkamp Agrisearch Equipment

2, Unscrew the cup in clockwise direction and empty it. Do not touch the
ceramic cup with your fingers. Wrap a clean towel around the cup.
The pressure sensor diaphragm is inside the small boring on the pressure
sensor body. It is very sensitive and may never be touched! It can be
destroyed even by slightest contact! No contamination should get on the
sealing and gasket.
3, If the cup is drained it should be drenched in distilled water overnight by
placing it in a beaker filled with water.
Important: There should be no water inside the cup. The cup must be in an
upright position so only the cup's outside is covered with water. Otherwise
cavities of air might be enclosed inside the ceramic.
4, The drenched cup should be empty. Insert the cup to the adapter and
connect it to the degassing device. Place the cup in water in an upright
position as described above.
5, Fill the other adapter capsule to the half with water and insert the
sensor body. Connect the adapter to the degassing device as well.
6, Start the vacuum pump. With drenched cups, the procedure will take 4 to 5
hours. From time to time, tap on cup and sensor body to loosen bubbles.
Degassing is complete when no air bubbles ascend from ceramic and body
and the cup is completely filled with water.
