HY-OPTIMA™ 720AS-GC Hydrogen Analyzing System - Product Highlight

Feb 26 2015

H2scan’s HY-OPTIMA 720AS-GC Hydrogen Analyzing System is designed to detect, measure and respond to hydrogen leaks in gas chromatography (GC) systems. The hydrogen specific solid-state sensing element is designed for long life, reliable operation, and for retrofit on all GC makes and models. The model 720AS-GC detects and measures hydrogen and provides alarm indications at a user selectable level. If hydrogen reaches the user selected alarm level, the alarm activates a light tower with a flashing red light, a buzzer and closes a valve to shut off the supply of hydrogen to the GC system. H2scan’s solution benefits customers and secures their safety with a quick response time, auto purge gas switch and visual & audible alarms.
