Model HP721C is a single-stage cylinder regulator in chrome-plated brass barstock for pressure control of non-corrosive gases when pressure rise is not critical. The Model 721CC is suitable for high-purity gas applications, research sample systems gases, process analyzer gases, gas chromatography, EPA protocol gases, laser gas systems and emission monitoring systems.
