About Product                                                                           

Application

    Differential pressure gauge is widely used to measure fan and blower pressures, filter resistance, air velocity, furnace pressure, orifice differential pressure, air bubbles and liquid water or hydraulic pressure amplifier, while the process is also used for combustion air gas ratio control and automatic valve control, and health care facilities in blood pressure and respiratory pressure monitoring.

   It is widely used in medical, microelectronics, aerospace, environmental engineering, biological engineering, pharmaceuticals, building intelligent, HVAC, food and beverage, precision electronic processing.
