High-technology manufacturing processes often require high-purity gases. The HPGP-101-C High Pressure Gas Probe System provides reliable in-line contamination monitoring for process gases at line pressure. The High Pressure Gas Probe System is compatible with oxygen, hydrogen and most non-toxic gases, and it can be used in many reactive gas monitoring applications. The High Pressure Gas Probe System speeds qualification of process gas distribution systems and detects particles in gases before they impact yield. The HPGP is paired with the Particle Data System, Ethernet (PDS-E) that collect and report data captured by the probe.
