Gas detector DG-P8R8/MR-Nstd CO2, measurement range on request, recommended temperature range 0-45°C, IR sensor DG-P8R8/MR-NSTD

Carbon dioxide detector for continuous monitoring

The DG-P8R8/MR-Nstd gas detector is an advanced device designed for continuous monitoring of carbon dioxide (CO2) concentration in indoor environments. It utilizes an infrared (IR) optical sensor, providing precise and reliable measurement. The detector is particularly useful in places where air quality control and safety are a priority – from industrial plants and logistics centers to public facilities.

Construction and functionality

The DG-P8R8/MR-Nstd detector works with a Digital Gas Detection System, enabling integration with a central supervisory module via an RS-485 network with the MODBUS RTU protocol. If defined CO2 concentration thresholds are exceeded, the detector signals an alarm optically and changes the state of the built-in relays. The measurement version transmits information about the current gas concentration to the supervisory module. The device is characterized by a replaceable sensor module, which simplifies maintenance, calibration and reduces operating costs. The detector is powered by 24V DC.

Application and benefits

• Wide range of applications: ideal for monitoring CO2 in industrial plants, logistics centers, public facilities and large rooms.
• Precise measurement: the IR sensor provides accurate and stable carbon dioxide concentration readings.
• Easy integration: RS-485 communication with the MODBUS RTU protocol enables seamless connection with control and supervision systems.
• Replaceable sensor module: simplifies maintenance and calibration, reducing operating costs.
• High reliability: a built-in microprocessor ensures stable device operation.
• Alarm signaling: optical alarm signaling and NO/NC relays inform about exceeding permissible CO2 levels.
• Compact dimensions: a housing with dimensions of 110 x 140 x 55 mm makes it easy to mount in various locations.
• 24V= power supply: ensures compatibility with commonly used power systems.

The DG-P8R8/MR-Nstd detector is intended for indoor use and should not be used in areas exposed to the risk of gas, vapor or dust explosions. The device is factory calibrated in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which guarantees the accuracy and reliability of measurements. The recommended operating temperature range is 0-45°C, making it suitable for most indoor environments.
