Environmental monitors designed to measure and display the concentration of ethylene oxide. These monitors typically include an ethylene oxide sensor (e.g. solid state), a control unit and a display; they may also include alarms activated at pre-fixed concentrations (e.g., 10, 20 ppm), recording capabilities, or a transmitter for remote central monitoring. Ethylene oxide environmental monitors are used mostly for continuous or periodic monitoring in hospital sterilizing rooms.
