ETO-A1 Ethylene Oxide Sensor ETO Sensor Description Alphasense is expanding its line of Electrochemical Toxic Gas Sensors to address industry-specific requirements, including emissions monitoring, process safety, environmental monitoring and VOCs. Ethylene Oxide (C2H4O) The ETO is a general purpose sensor, primarily developed for monitoring Ethylene Oxide but also capable of measuring other volatile organic compounds (VOCs). Our toxic evaluation board allows easy adjustment of the bias voltage to optimise this sensor for the required application. See application note AAN113.
