Gas detector DG-P8R/MR CO2, 5% v/v, IR sensor

Carbon dioxide detector for continuous gas concentration monitoring

The DG-P8R/MR gas detector is an advanced device designed for continuous monitoring of carbon dioxide (CO2) levels in premises. It utilizes an optical sensor based on infrared (IR) technology, ensuring precise gas concentration measurement up to 5% by volume. The detector is compatible with the Digital Gas Detection System, enabling integration with other devices and a central monitoring system.

Versatile application and reliability

The device finds application in industrial plants, logistics centers, public facilities, and large rooms where control of CO2 concentration is crucial for safety and comfort. Thanks to the replaceable sensor module, the detector is easy to maintain and calibrate, which translates into lower operating costs. It is worth emphasizing that the detector is not intended for use in potentially explosive atmospheres.

Key features and functionality

• RS-485 communication: Provides reliable data transmission to the monitoring system using the MODBUS RTU protocol.
• Two alarm thresholds or measurement mode: Allows configuration of the device to operate in threshold mode with alarm signaling or measurement mode with reading of the concentration value.
• Built-in relays: Two relays with NO/NC contacts on a removable board allow direct control of external devices or audible and visual signaling.
• Replaceable sensor module: Facilitates maintenance, calibration and sensor replacement in case of failure or the need to change the measurement range. Modules are compatible with DG/F and DG/P series.
• Thermal compensation: Ensures measurement stability regardless of changes in ambient temperature.
• Alarm history: Enables analysis of events and identification of potential problems.
• Semi-automatic addressing: Facilitates configuration of the detector in a digital network without the need to open the housing.
• Screwless terminals: Allow quick and easy wiring without the use of tools.
• Configuration with DETnet View software: Allows remote setting of detector parameters and monitoring of its operation (software available on the manufacturer's website).
• Calibration: All detectors are factory calibrated in their own GAZEX Calibrating Laboratory accredited in accordance with PN-EN ISO/IEC 17025 (PCA accreditation no. AP150).

The DG-P8R/MR detector is a solid and precise tool for monitoring carbon dioxide concentration, which will meet the expectations of both professional installers and end-users looking for a reliable gas detection system. The device is characterized by ease of installation, configuration and low operating costs thanks to replaceable sensor modules.
