DESCRIBE

Model A71 differential pressure gauge is made of high-quality anti-corrosion stainless steel. It not only adopts all metal structure, but also has a closely combined pressure measuring diaphragm to achieve high overpressure safety. Because of its high-grade stainless steel structure and robust design, the pressure gauge is very suitable for chemical and processing engineering fields. This type of pressure gauge can be used not only for gas or liquid media, but also for corrosive environments. We provide a variety of liquid receiving parts made of special materials, such as Monel or Hastelloy. The measuring range of the instrument is 0... 6KPa to 0... 4 MPa, which can meet the requirements of a wide range of applications.
