7ETO-10 Ethylene Oxide (EO) Gas Sensor For Medical Sterilization Post-Ventilatio

Product Specification

7ETO-10 Ethylene Oxide (EO) Gas Sensor For Medical Sterilization Post-Ventilation Monitoring Portable Occupational Safety Detectors

1. Product Overview:

The 7ETO-10 is a compact, high-performance ethylene oxide (EO/ETO) gas sensor tailored for low-concentration EO detection scenarios. It adopts advanced electrochemical sensing technology to deliver reliable, real-time monitoring of EO—critical for applications where even trace EO leaks pose health, safety, or regulatory risks. With a focus on miniaturization and cost-effectiveness, it balances precision with easy integration into portable detectors, small-scale monitoring systems, and point-of-use safety devices.

2. Core Features:

• Low-Concentration Detection Expertise: Optimized for trace EO monitoring, with a detection range of 0~10 ppm—ideal for environments requiring strict control of EO levels (e.g., post-sterilization ventilation, occupational safety).
• High Precision & Selectivity: Achieves a resolution of ≤0.05 ppm and accuracy of ±3% FS (or ±0.1 ppm, whichever is larger), ensuring accurate identification of minimal EO concentration changes. Its three-electrode electrochemical structure effectively resists interference from water vapor, CO₂, ethanol, and other common background gases.
• Rapid Response & Recovery: Features a T90 response time of ≤25 seconds and T10 recovery time of ≤50 seconds, enabling fast alerts for sudden EO leaks and minimizing exposure risks.
• Compact & Lightweight Design: With dimensions as small as 35×25×15 mm (L×W×H) and weight ≤20 g (ABS housing), it fits easily into portable devices (e.g., handheld EO detectors) and space-constrained fixed installations.
• Flexible Integration: Supports standard low-power analog outputs (0~3 V DC or 2~10 mA DC) and optional digital output (I2C), compatible with microcontrollers, small PLCs, and portable instrument circuits.
• Stable & Long-Lasting Performance: Boasts a typical operational lifespan of ≥2 years (under continuous use in clean air with EO <0.5 ppm) and low signal drift (≤1% FS/year), reducing maintenance frequency and total cost of ownership.
• Wide Environmental Adaptability: Operates reliably in temperatures from -5℃ to 45℃ and humidity from 20% to 85% RH (non-condensing), suitable for indoor medical, pharmaceutical, and laboratory environments.

3. Typical Applications:

• Medical Sterilization Post-Ventilation Monitoring: Installed in hospitals, clinics, or medical device factories to verify EO residue levels in sterilized equipment (e.g., surgical instruments) and sterilization room air after ventilation—ensuring compliance with standards like ISO 10993-7.
• Portable Occupational Safety Detectors: Integrated into handheld devices for workers in EO-related industries (e.g., pharmaceutical manufacturing, chemical logistics) to provide real-time personal EO exposure monitoring (meeting occupational exposure limits such as OSHA’s 1 ppm 8-hour TWA).
• Small-Scale Pharmaceutical Production: Used in lab-scale or small-batch sterilization processes (e.g., sterile APIs, medical dressings) to monitor EO concentration in closed production chambers, ensuring sterilization efficacy and worker safety.
• Laboratory & R&D Environments: Deployed in chemical labs conducting EO-based research (e.g., material modification, microbial sterilization studies) to track EO levels in fume hoods or experimental spaces, protecting researchers from toxic exposure.
• Household/Commercial Sterilizer Monitoring: Integrated into small EO sterilizers for household medical supplies (e.g., dental tools) or commercial small-appliance sterilization devices to detect post-sterilization EO leaks, ensuring user safety.
