1、Use of Pressure-meter Gear Drive
　　 Our pressure-gauge gear drives mechanism(Shorted Form:Pressure-gauge mechanical core)are applied to special pressure-gauges,such as diaphragm-box pressure-gauge,diaphragm-flake pressure-gauge,double-pointers double-pipes pressure-gauge,aseismatic pressure-gauge,corrosion-resisting pressure-gauge,tyre pressure-gauge,different pressure-gauge,etc,and normal pressure-gauges.
