Toxic Gas Sensor
for pharmaceutical ethylene oxide monitoring
Application:
For ETO detection in petroleum, petrochemical, pharmaceutical production and environmental production fields.Product characteristics:
Anti-jammingDescription
MQ-E3-ETO ethylene oxide sensor is a constant potential electrolytic sensor. Ethylene oxide and oxygen undergo corresponding redox reactions on the working electrode and counter electrode, releasing charges and forming a current. The magnitude of the current is proportional to the concentration of ethylene oxide. The concentration of ethylene oxide can be determined by measuring the magnitude of the current.
