ETO-B1 Ethylene Oxide Sensor

EtO Gas Sensor, Electrochemical, B-Series, 0–100 ppm range

High-stability ethylene oxide sensor for fixed safety and process systems

The ETO-B1 is a 0–100 ppm ethylene oxide sensor in the B-Series package, intended for fixed gas detection, leak monitoring and process control in sterilisation plants, medical facilities and industrial EtO users. With 2000–3400 nA / ppm sensitivity and T90 < 200 s, it provides strong, stable output across a wide temperature range. Operating life exceeds 24 months (24-month warranted), making ETO-B1 a durable choice for continuous EtO monitoring.
