I picked up a Heise high resolution gauge the other day that I want to use for PP mixing. It has a 4inch face and will register 2000 psi each time around the face. It will go around twice for 4000 PSI. The resolution is 5 PSI and the face is adjustable to set zero - it's a sweet setup.
I thought they typically used stainless steel tubes for high pressures but there is a label on the face that the tube is beryllium copper. I believe it should be O2 compatible but there is also a label on the back "Not for oxygen service". Is this a warning because it was not O2 cleaned during mfg or did I miss something in the O2 compatibility of materials?
It was originally used for GN2 (gaseous nitrogen).
Thanks,
Jeff
