Application description:
The ammonia pressure gauge  can be used in measuring the pressure of the service medium which has no corrosion functiontoall of the carbon steel,stainless and solders like tin.Mainly used in measuring the pressure of the liquid or gas of the ammonia which will be conce r n e d in fertilization manufacture and the refrigeration equipment.
Structure:
The gauge is made up of measuring pressure system(involve connector,bourdon tube).gear setting,pointer setting and outer case.

When the service medium act on the flexibility parts and make it move,with the help of the stick,magnified by the gear setting,and the pointer point it out on the dial.
