Gas detector DG-9E5/M oxygen, 19/18 % v/v, electrochemical sensor, 5-year lifespan, RoHS

Gas Detectors – Reliable Atmosphere Monitoring

Digital gas detectors from the DG/M series, such as the DG-9E5/M model, are designed for continuous monitoring of gas concentrations in various environments. They detect hazardous oxygen levels, ensuring safety in industrial facilities, logistics centers, and public utility installations. This detector employs an electrochemical sensor known for high measurement accuracy and stability.

Detectors from the DG/M series integrate with the Digital Gas Detection System, enabling centralized supervision and rapid response in case of an alarm. Upon exceeding permissible oxygen concentration thresholds, the detector signals the event visually via a built-in LED and transmits data to the monitoring module via an RS-485 interface using the MODBUS RTU protocol.

Design and Functionality

The DG-9E5/M detector features a modular design. The replaceable sensor module simplifies maintenance, calibration, and reduces operational costs. The built-in microprocessor ensures reliable and stable operation. Additionally, the detector includes a thermal compensation system and an alarm history log, facilitating event analysis and optimization of the gas detection system. The splash-proof housing (IP44), made from high-impact ABS, protects the device against mechanical damage and external environmental factors. Two cable entries simplify connecting multiple detectors into a network.

Applications and Benefits

• Oxygen Concentration Monitoring: The DG-9E5/M detector is specifically designed for precise measurement of oxygen concentration in the range of 19–18% by volume (v/v). This is critical in environments where oxygen deficiency or excess may pose a threat to health or life.
• Rapid Hazard Response: Thanks to its electrochemical sensor and fast response time, the detector instantly alerts users when oxygen concentration limits are exceeded.
• Easy System Integration: RS-485 communication with MODBUS RTU protocol enables seamless integration with existing monitoring and control systems.
• Low Operational Costs: The replaceable sensor module allows quick replacement of faulty components without replacing the entire detector, significantly reducing system maintenance costs.
• Calibration: All GAZEX detectors are calibrated in our own Calibration Laboratory operating in accordance with PN-EN ISO/IEC 17025 (accredited by PCA, certificate no. AP150), guaranteeing measurement accuracy and reliability.
• Long Sensor Lifespan: The electrochemical sensor has a service life of 5 years, minimizing the need for frequent replacements and ensuring long-term device reliability.

The DG-9E5/M detector is a reliable tool for gas detection system installers and end-users seeking an effective solution for monitoring atmospheres in potentially hazardous environments.
