The HC80 is a precision helium flow and chamber-purge controller engineered to maintain a known, stable helium-filled segment in beamline systems. It automates startup, chamber purge and sustain modes, monitors helium concentration, chamber pressure, residual oxygen, temperature and orientation, and provides interlock outputs and logging for complete operational visibility. With dual mass flow controllers, stainless-steel internal pipework, front-panel and remote browser interface control it’s built for demanding installations where reliable gas management and safety integration are essential.
