Pressure vessels

Pressure vessels are sealed containers and the instruments that monitor them, built to hold or measure fluids and gases at pressures above or below ambient. In laboratory and process settings the term covers both the containment, such as stainless steel vessels rated for sustained internal pressure, and the sensing hardware that reads it. Of the current Questpair listings, 97 percent are used, drawn from 173 items across 10 verified suppliers in 6 countries. New, used and refurbished units all appear, with gauges and transducers forming the larger share and the vessels themselves fewer in number. Prices span a wide band because a bare gauge and a complete vessel sit far apart on it.
