Tensio 120 - Septum tensiometer

The Septum tensiometer permits to read out several tensiometers using only one instrument and therefore offers a favourably priced alternate solution to the comprehensive determination of soil moisture tension with many measurement points. The topside of the tensiometer is sealed with a silicone septum so that the hand meter can be attached quickly and simply by a needle. The septum recloses automatically when the meter is removed. It can be replaced simply because it is screwed on using a GL18 thread or used as a silicon plug depending on design. The ceramic cup (P80; 20 x 50 mm) is mounted on a transparent acrylic tube (Ø 20 mm) with level scale. It is therefore easy to read the level of the tensiometer.



  • simple to handle
  • favourably priced because only one measurement instrument is required
  • variable lengths in accordance with the measurement
