Enmet's GSM-60 is a hazardous gas monitoring system with an internal sampling pump. It uses internal sensors and remote sensor transmitters to continuously monitor up to four gases. The instrument can use an array of sensor technologies, infrared (IR), electrochemical (EC), photoionization detector (PID), metal oxide semiconductor (MOS) and catalytic (CAT). GSM-60 can be configured to monitor chemicals in ambient air including VOCs, carbon monoxide, carbon dioxide, oxygen, trace hydrocarbons and other toxic and industrial gases. GSM-60 can also monitor 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 headspaces of tanks, HVAC ductwork, VOC scrubber exhausts and wastewater treatment plants. GSM-60 is used in industrial applications ranging from medical and pharmaceutical to aerospace and process manufacturing.
