Gas detector DG-8R8/MR CO2, 0.5/1.5 %v/v, recommended temperature range 0-45 °C, IR sensor

Gas detectors – reliable safety in any environment

The DG/MR series detectors are advanced devices designed for continuous monitoring of gas concentrations in rooms. Control is carried out by precise measurement of the content of a given gas in the surrounding air. If defined thresholds are exceeded, the detector activates a visual alarm signal, changes the state of built-in relays, and transmits information to the central supervisory module via the RS-485 network. These devices are perfect for gas detection systems, providing a quick response and minimizing risk.

Application and functionality

The DG-8R8/MR detector, equipped with an optical sensor (Infra-Red), is designed to detect carbon dioxide (CO2) in the range of 0.5/1.5 %v/v. The recommended operating temperature range is 0-45°C, making it suitable for use in various environmental conditions. The device finds application in industrial plants, logistics centers, public utility facilities, and large rooms exposed to emissions of toxic or explosive gases. Thanks to the replaceable sensor module, maintenance and calibration of the detector are simple and economical.

Key features and benefits

• Replaceable sensor module: Enables quick replacement of a damaged sensor or adaptation to other measurement needs – reduces operating costs and simplifies servicing.
• RS-485 communication: Provides reliable data transmission to the supervisory system using the standard MODBUS RTU protocol.
• Two alarm thresholds: Allow precise setting of warning levels and reaction to changes in gas concentration.
• Built-in relays: Enable direct control of external devices (e.g., shut-off valves) in the event of a dangerous gas concentration being detected.
• Optical signaling: Clear alarm signaling provides a quick warning of danger.
• Solid construction: The housing made of high-impact ABS/PC ensures durability and resistance to mechanical damage.
• Thermal compensation: Ensures measurement accuracy even at variable ambient temperatures.
• Semi-automatic addressing: Facilitates integration of the detector into a digital network without the need to open the housing.

The DG-8R8/MR detector is a device of conventional construction and should not be used in places threatened by the explosion of gases, vapors or dusts. Let's remember this during installation and use! The device is factory calibrated in accordance with the PN-EN ISO/IEC 17025 standard by the GAZEX Calibration Laboratory (PCA accreditation No. AP150), which guarantees its accuracy and reliability of measurements.
