The ME4 ETO Ethylene Oxide Gas Sensor is an electrochemical toxic gas sensor specifically designed to detect ethylene oxide (ETO) at low concentrations with high accuracy.
Ethylene oxide is a highly reactive and toxic gas commonly used in chemical processing, sterilization, and industrial manufacturing, making reliable detection essential for worker safety and environmental protection.
This sensor operates using constant potential electrolysis, where an oxidation-reduction reaction occurs when ethylene oxide molecules reach the sensing electrode. The reaction produces an electrical current that is directly proportional to the gas concentration, allowing detection systems to measure ETO levels precisely.
Because of its linear output signal, fast response time, and high sensitivity, the ME4 ETO sensor is widely integrated into gas analyzers, portable gas monitors, industrial safety systems, and environmental monitoring equipment.
