A2 series differential pressure gauge is a pressure gauge which use rubber diaphragm as the sensing element and simple, non-friction magnetic spiral movement to measure pressure. It can use the pointer quickly indicate the measured gas pressure, whether it is positive pressure, negative pressure or differential pressure. The design is anti-shocking, anti-shaking and anti-over pressure. A2 differential pressure gauge is widely used in the fan and blower pressures, filter resistance, air velocity, furnace pressure, orifice differential pressure, bubble level and liquid pressure amplifier or hydraulic system and it is also used in combustion air gas ratio control and automatic valve control and blood pressure and respiratory pressure monitoring in health care facilities.
