We use the barometer holder in an experiment where we examine hydrostatic pressure using barometer. From the barometer leads a tube which is about 47 cm long. The problem solved by our holder lies in the fact that the tube itself twists and rotates. It is, therefore, difficult to immerse the tube in liquid and ensure the tube to be immersed upright and not to twist itself. Therefore, the tube is comfortably attached to the holder and the holder guarantees that the tube does not bend at all. Another advantage of this holder is the scale divided by centimetres, according to which we can directly read the depth into which the tube is immersed and do not add complicatedly any rulers or other aids to it at all.
