Ok, I have a question. I am wondering if:
A) there is such a thing as a combination vacuum and pressure gauge and
B) if not, would there be any harm to the separate gauges if you have a vacuum and a pressure gauge hooked to the same vessel and that vessel is under pressure sometimes and has a vacuum other times
?
Does that make ANY sense?
BTW, I'm talking pressure of less than 50 psi and vacuum approaching 30 inches.
