SS21ETO Ethylene Oxide Sensor – Industrial-Grade Detection for EO Safety and Process Monitoring
SS21ETO is a high-accuracy electrochemical sensor designed to detect ethylene oxide (C₂H₄O) gas in the range of 0 to 20 ppm.
It delivers a linear output of 270 ± 70 nA/ppm, fast T90 response under 200 seconds, and a resolution of ≤0.5 ppm.
The sensor has minimal cross-sensitivity to common gases such as hydrogen, ammonia, and toluene, ensuring reliable operation in complex environments.
It is optimized for EO sterilization, chemical manufacturing safety, and integration into fixed gas detection systems.
With a 24-month lifespan and robust performance, it is ideal for harsh industrial environments.
