Magnehelic Gauges
Description
Differential pressure Gauges are widely utilized for measuring pressure of fan and blowing machine, resistance of filter, wind speed, furnace pressure, differential pressure of pore plate, the pressure of drum water level, liquid amplifier and hydraulic pressure system. Meantime, they are used to control the automatic valve and specific value of air-producer gas in combustion and they are used to test blood pressure and respiratory pressure in medical health care equipment. The key component adopt import materials.
