The manometers are measuring instruments for pressure. There are two types of pressure manometers suitable for different uses and precisely:
- Pressure dry (fillable)
- Manometers with glycerine.
The latter have the crate filled with glycerin, in order to damp the oscillations of the needle and limit the wear of moving parts, thus making these instruments suitable for use in the presence of vibrations and improving the resistance to pressure buttons.
