Cheap differential pressure gauge indicator  

Application of differential pressure gauge indicator :
For high accuracy-graranteed within 2% of full scale. indicate low air or non-corrosive gas pressures –eighter positive, negative(vacuum)of differential. The design resists shock ,vibration and over-pressures no Manometer fluid to evaporate,  freeze or cause toxic or leveling problems, it’s inexpensive too .
