מיני טנסיומטר מכאני (לעציצים, מצע מנותק. עומק רדוד)

The mechanical tensiometer is made up of a plastic tube with a transparent part in its upper segment, whereas a porous ceramic dome is connected to its bottom end. Into its uppermost end is screwed a mechanical vacuum meter in the shape of a watch with a hand.

All what you have to choose is the depth of the tensiometer in order for the ceramic at the bottom (middle of the ceramic) to be at the uppermost level of the roots of the plant, or the middle part of the roots, or the deepest level of the roots. Since it is a mini tensiometer meant for a slam plant, one apparatus will suffice in order to obtain data that will allow deciding on the timing and amount of the irrigation. As a standard, we provide tensiometers at depths of 15 and 20 cm. The tubes are made of PVC having an outer diameter of 12 mm. The length indicated is not the physical length of the tube, but that of the tube that is appropriate for installing at the desired depth. We provide a label indicating the depth, whereas the label is at the level of the surface of the soil.
