IsoMon Dual-Channel Gas Detection

ATi’s IsoMon dual-channel gas detection system has revolutionised the way sterilisation cycles are processed, monitoring the complete decontamination process from start to finish and measuring gas levels of both high and low concentration.

This unique system has been primarily developed to address the sterilisation needs of the pharmaceutical, biological, medical device manufacturing, defence, industrial, healthcare and food packaging industries, but can also be deployed to reduce the occurrence of hospital-acquired infections and even the decontamination of aircraft cabins.
