Continuous ETO Gas Leak Monitor Ethylene Oxide Detector for Medical Sterilizatio

The ETO Gas Leak Monitor is a continuous ethylene oxide detector engineered for medical sterilization and disinfection workshops. It delivers reliable, real-time monitoring of ethylene oxide concentrations to help safeguard personnel and maintain a controlled, compliant working environment.

SG100 is a cost-effective, IECEx & ATEX-certified explosion-proof fixed online gas transmitter specially built for ethylene-oxide (ETO) monitoring in disinfection and sterilization-industry sites. It supports selectable electrochemical or PID sensor, with measuring ranges 0-10/50/100ppm and resolution options 0.01ppm / 0.1ppm. Featuring IP66/IP68 ingress protection, intelligent plug-and-play sensor module, multiple standard signal outputs and optional wireless transmission, it supports magnetic remote operation. This unit simplifies field installation and routine maintenance and delivers reliable 24-hour continuous gas concentration monitoring for medical-sterilization-related facilities.

Ethylene-oxide is an efficient low-temperature sterilizing agent widely adopted in medical-device disinfection workshops. ETO is toxic and flammable; long-term occupational exposure brings serious health hazards to on-site staff. Continuous real-time monitoring helps control ETO residual concentration and protects operators in disinfection-production environments.
