4ETO - 500 Gas Sensor For Medical Sterilization Monitoring Industrial Safety Monitoring
Product Applications:
The 4ETO-500 gas sensor is an electrochemical ethylene oxide (ETO) sensor primarily designed for:
- Medical Sterilization Monitoring
- Detecting ETO leaks in hospital and clinical sterilization systems, suitable for fixed or portable detection equipment.
- Industrial Safety Monitoring
- Applied in coal mines, chemical plants, and organic volatile gas monitoring to ensure production safety.
- Environmental & Storage Control
- Used for ETO concentration detection in fruit storage environments to maintain freshness and safety.
Product Features:
- Wide Measurement Range
- Nominal range: 0–500 ppm; maximum overload: 1,000 ppm, suitable for various ETO concentration detection scenarios.
- High Sensitivity
- Sensitivity: 0.058 ± 0.033 μA/ppm, enabling precise detection of subtle ETO concentration changes.
- Rapid Response
- Response time (T90): ≤120 seconds, ensuring timely feedback for leak alarms.
- Strong Environmental Adaptability
- Operating temperature: -20°C–50°C; humidity: 15%–90% rh (non-condensing); pressure: 1 ± 0.1 atm, suitable for harsh industrial and indoor environments.
- Excellent Linearity
- Linear output within 0–500 ppm, facilitating accurate data measurement and signal processing.
- Long Service Life
- Expected operating life: 2 years in clean air (long-term output drift <2% signal/month); storage life: 6 months in original packaging, ensuring stability and reliability.
- Easy Installation & Replacement
- Pin-to-pin replacement for standard 4-series ETO sensors from other manufacturers, allowing seamless integration into existing equipment designs.
