Ethylene Oxide (EtO) Detectors

Protect your staff and maintain compliance in healthcare, sterilisation, and chemical industries with our fixed and portable ethylene oxide detection systems.

Detection is typically achieved using electrochemical sensors with high sensitivity to low parts-per-million levels. These sensors deliver fast response times and stable readings, with routine calibration ensuring long-term reliability and compliance with occupational exposure limits.

Ethylene oxide (EtO) is a colourless, highly reactive gas used in sterilisation, medical equipment processing, and chemical manufacturing. While essential in these applications, EtO is both flammable and toxic, with recognised carcinogenic properties. Short-term exposure can cause respiratory irritation, nausea, and headaches, while long-term exposure increases the risk of neurological effects and cancer. Because it is colourless and often odourless at hazardous concentrations, reliable detection is critical wherever EtO is handled.
