Ethylene oxide gas detector DG-P0E.ETO/M, 20ppm (cross-calibration), electrochemical sensor

Ethylene Oxide Detector – Reliable Monitoring and Protection

The DG-P0E.ETO/M gas detector is an advanced device designed for continuous monitoring of ethylene oxide concentration in the air. It utilizes an electrochemical sensor, providing precise measurements even at low concentrations – up to 20 ppm. The detector is a key element of gas detection systems, finding application in industrial plants, logistics centers, and public facilities where the presence of this gas may pose a hazard.

Design and Operating Principle

The DG-P0E.ETO/M detector is based on a replaceable module with an electrochemical sensor. This design simplifies maintenance, streamlines calibration, and reduces operating costs – if necessary, only the sensor module needs to be replaced, without the need to replace the entire device. A built-in microprocessor ensures stable and reliable operation, and a temperature compensation system minimizes the impact of temperature changes on measurement accuracy. In the event of exceeding the permissible ethylene oxide concentration, an optical alarm signal is activated and information is sent to the digital supervisory module via the RS-485 interface with the MODBUS RTU protocol.

Application and Benefits

• Wide range of applications: ideal for monitoring ethylene oxide concentration in various industrial and public facilities.
• High measurement accuracy: the electrochemical sensor guarantees accurate results even at low gas concentrations (up to 20 ppm).
• Easy maintenance: the replaceable sensor module design simplifies servicing and reduces operating costs.
• Reliability and stability: the built-in microprocessor ensures stable device operation.
• Digital communication: the RS-485 interface with the MODBUS RTU protocol enables integration with supervisory systems.
• Cross-sensitivity calibration: the possibility of cross-sensitivity calibration increases the flexibility of using the detector in various environmental conditions. However, it should be remembered that cross-sensitivity calibration may affect the measurement accuracy (the measurement error may be greater than ±20%).
• Splash-proof housing (IP44): provides protection against moisture and dust, allowing installation in harsh industrial conditions.
• Alarm history: allows for analysis of events and identification of potential problems.

The DG-P0E.ETO/M detector is factory calibrated in its own GAZEX Calibration Laboratory, operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which guarantees its metrological reliability. The device is not intended for use in areas hazardous due to the explosion of gases, vapors or dust – it has a standard construction.
