Hazardous-gas detection with an array of sensor options

| By Chemical Engineering



The GSM-60 hazardous-gas monitoring system (photo) is designed with an internal sampling pump and can use both internal sensors and remote sensor transmitters to continuously monitor up to four gases. The instrument is capable of utilizing an array of sensor technologies: infrared (IR), electrochemical (EC), photoionization detector (PID), metal oxide semiconductor (MOS), and catalytic (CAT). The GSM-60 can be configured to monitor a wide range of chemicals in ambient air, including volatile organic compounds (VOCs), carbon monoxide, carbon dioxide, oxygen, trace hydrocarbons, as well as many toxic and industrial gases. Additionally, the GSM-60 is capable of monitoring reactive gases, such as arsine, chlorine dioxide, ethylene oxide, hydrogen fluoride and ozone. The system is designed for monitoring ambient air in difficult environments, including the headspaces of tanks, HVAC ductwork, VOC-scrubber exhausts and wastewater-treatment plants. — Enmet, LLC, Ann Arbor, Mich.
