The Eco Celli Barometer works on the basis of gas pressure inside the barometer tube (red liquid. The red liquid in the right side of the U-shaped tube will react to changes in air pressure. When air pressure is high, the liquid will be pushed downwards. At low air pressure, the liquid will rise in the tube.
However, temperature also affects the barometer - this causes the thermometer ( blue liquid) to make a correction. In the centre is a scale that can be moved up and down. When the temperature changes, one needs to adjust the position of the scale and can then read the air pressure.
