Model HP 741-125-330-AD Ultra-High Purity Regulator

Model HP 741 is a single-stage cylinder regulator in stainless steel for applications where a slight rise in delivery pressure from full to empty single-stage cylinder can be tolerated. The Model HP 741 regulator is suitable for corrosive gas applications, high-purity gas applications, research sample systems gases, process analyzer gases, gas chromatography, EPA protocol gases, laser gas systems and emission monitoring systems. Recommended for corrosive gases or purity levels of Grade 6.0 (99.9999) and higher.
