Hey guys, I was wondering if anyone knew where I could buy tank gauges that read both the pressure and temperature inside the tank. They can be digital, in fact if it is cheap enough it would be preferred. Does anybody have any ideas? Northern Tool at least the one here didn't, Lowe's didn't, and Home Depot didn't. Scuba shops have some but not at the ranges I need (1-50psi and 0- ~500 degrees F).
