Required to install the pressure gauge in a confined space. No exact calibration required, just a rough idea of the pressure. A test device of + or - 2 psi must be provided. Installation of a natural gas pipeline with compressed air. The sensor I received worked very well. (If I had to do it again, I would allow more space and order a 2" pad; however, it would be easier for an elderly person like me to read).
