How To Choose The Type Of Pressure Gauge

The type of manometer is selected according to the pressure of the medium under test, the display requirements of the pressure indicator and the physical and chemical properties of the medium. If the measurement of micro pressure, obviously can not choose to measure the greater pressure of the spring tube manometer, and can only use inclined micro manometer or membrane box manometer; For the measured medium pressure is not too large do not require rapid reading, often choose u-type pressure gauge or single tube pressure gauge; If the pressure is above 49kPa, the spring tube manometer shall be generally used. The measured medium pressure is small, and the requirements can quickly read the value, can choose the membrane box pressure gauge
