Product Description:

YJJ ETO/M-10 Ethylene Oxide Electrochemical Gas Sensor 0-10ppm for Medical Sterilization Industry

Features:

I. Basic Information

Model: ETO/M-10

III. Core Product Advantages

High Selectivity: Specific response to ethylene oxide, extremely low cross-interference from ethanol, formaldehyde, and low-concentration CO, significantly reducing false alarms in disinfection workshops；

Ultra-Wide Temperature Range Operation: Stable output even in extremely low temperature environments, suitable for cold storage and low-temperature sterilization equipment；

Ultra-High Resolution: 0.05 ppm resolution capability, meeting extremely low concentration safety monitoring requirements for occupational hygiene；

Universal Standardized Pin: 4-pin universal packaging, no need to modify the board for customers' existing detectors, direct replacement is possible；

Stable Low Drift: Three-electrode structure suppresses temperature and humidity drift, small zero-point offset over long-term use, long calibration cycle.
