Gas detector DG-PV8R8-Nstd CO2, measurement range on request, recommended temperature range 0-45°C, IR sensor DG-PV8R8-NSTD

Carbon dioxide detector for continuous gas concentration monitoring

The DG-PV8R8-Nstd gas detector is an advanced device designed for continuous measurement of carbon dioxide (CO2) concentration in enclosed and industrial spaces. It utilizes an infrared (IR) optical sensor, providing precise and reliable measurement results up to 2% by volume. The device is particularly useful in places where control of CO2 levels is critical for safety and comfort, such as greenhouses, warehouses, underground parking lots, ventilation systems, or utility rooms.

Construction and functionality

The DG-PV8R8-Nstd detector stands out for its versatility thanks to two signal outputs – current 4-20 mA and voltage 2-10 V. This allows easy integration with various control and monitoring systems, regardless of the manufacturer. Built-in optical signaling (two LEDs) informs about exceeding the permissible CO2 concentration values. Additionally, the detector has functions of operating time counter, emergency status history, and calibration deadline signaling. The use of a replaceable sensor module facilitates servicing and calibration of the device, and also allows it to be adapted to different measurement needs.

Applications and benefits

• Precise CO2 measurement: The IR sensor provides accurate and stable carbon dioxide concentration readings.
• Versatility: Two signal outputs (4-20 mA and 2-10 V) allow integration with various control systems.
• Replaceable sensor: Facilitates maintenance, calibration and adaptation to other gases (using the appropriate module).
• Built-in diagnostic functions: Operating time counter, failure history and calibration signaling increase reliability and facilitate servicing.
• Optical signaling: Two LEDs indicate exceeding the permissible CO2 standards.
• Thermal compensation: Ensures measurement stability even under changing environmental conditions.
• Solid construction: A housing made of high-impact ABS/PC ensures durability and resistance to mechanical damage (IP54 for electronics, IP44 for sensor cover).
• Calibration: All detectors are calibrated in their own GAZEX Calibration Laboratory accredited in accordance with PN-EN ISO/IEC 17025.

The DG-PV8R8-Nstd detector is an ideal solution for both professional installers of gas detection systems and end-users looking for a reliable tool to monitor air quality and ensure safe working or usage conditions. The device is characterized by easy installation and configuration and high measurement accuracy, making it an excellent choice for a wide range of industrial and commercial applications. The recommended operating temperature range is 0-45°C, which ensures proper operation under typical environmental conditions.
