4ETO-10 Ethylene Oxide Gas Sensor For Medical Device Sterilization Monitoring

Product Specification

                 4ETO-10 Ethylene Oxide Gas Sensor For Medical Device Sterilization Monitoring Pharmaceutical Industry

1. Product Features:

• Precise Concentration Detection: Offers a measuring range of 0-10ppm with a resolution of 0.1ppm, enabling accurate capture of trace ethylene oxide (ETO) levels, which is critical for scenarios requiring strict ETO monitoring.
• Stable Performance: Boasts excellent long-term stability, with a monthly signal change of less than 2%. Meanwhile, its baseline drift only equals a 0-2ppm concentration variation within the operating temperature range of -20℃ to 50℃, ensuring reliable and consistent data output.
• Linear Output Characteristic: Features a linear output response, which simplifies subsequent data processing and calibration procedures for the connected monitoring systems, reducing the complexity of signal analysis.
• Broad Environmental Adaptability: Operates normally in a temperature range of -20℃ to 50℃ and a relative humidity range of 15%-90% (non-condensing), and is compatible with a working pressure of 90kPa-110kPa. This allows it to adapt to various indoor and outdoor application environments.
• Compact & Lightweight Design: Weighs approximately 5 grams with a small overall size. The compact structure facilitates easy integration into different types of gas detection devices or equipment, without occupying excessive installation space.
• High Compatibility: Serves as a pin-to-pin replacement for standard four-series ethylene oxide electrochemical sensors. This ensures seamless substitution in existing sensor systems, saving the cost and effort of modifying the device’s circuit or installation structure.

2. Application Scope:

• Medical Device Sterilization Monitoring: Ethylene oxide is widely used for sterilizing medical devices (such as surgical instruments, disposable medical supplies). The 4ETO-10 sensor can monitor residual ETO concentrations in the sterilization chamber or in the post-sterilization ventilation process, ensuring that the residual amount meets safety standards to avoid potential harm to medical staff and patients.
• Pharmaceutical Industry: Applied in pharmaceutical production workshops, especially in areas where ETO is used for sterilizing  packaging or pharmaceutical raw materials. It helps monitor the ETO concentration in the workshop air to ensure compliance with pharmaceutical production environmental safety regulations.
• Food Processing & Storage: In some food processing scenarios where ETO is used for mold prevention and sterilization (e.g., certain dried fruits, canned foods), the sensor can detect residual ETO in the food storage environment or on the food surface, preventing excessive ETO residues from affecting food safety.
• Industrial Safety Monitoring: Used in industrial plants that produce, transport, or use ethylene oxide (such as chemical plants manufacturing ETO). It monitors the ETO concentration in the workshop or around storage tanks to promptly alert against gas leaks, protecting the safety of on-site workers and preventing fire or explosion risks caused by ETO accumulation.
• Environmental Air Quality Detection: Deployed in environmental monitoring stations or in areas near ETO-related enterprises to monitor the concentration of ETO in the ambient air, assisting in evaluating the impact of ETO emissions on the surrounding environment and human health.
