Gas detector DG-P0E.NO2/N NO2, 20ppm, electrochemical sensor

Gas detectors DG/P – reliable measurement and protection

The DG/P series gas detectors are devices designed for continuous monitoring of toxic and explosive gas concentrations in industrial environments. They are used in enclosed spaces where the presence of harmful substances may pose a threat to health and life. Model DG-P0E.NO2/N is dedicated to the precise measurement of nitrogen dioxide (NO2) in a range of up to 20 ppm.

Wide application and compatibility

The DG-P0E.NO2/N detector, thanks to its 4-20mA analog output, is compatible with various control and signaling systems. It can be integrated with both dedicated GAZEX control modules (MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16, MDD-1, MDD-1/T, MDD-1x/T) and central units from other manufacturers accepting a standard current signal. This flexible solution allows the detector to be adapted to the existing infrastructure.

Constructional and operational features

The DG-P0E.NO2/N detector is characterized by a solid construction with a splash-proof housing (IP44). It is equipped with a replaceable electrochemical sensor, which ensures easy maintenance and calibration and reduces operating costs. Replacing the sensor does not require calibration at the installation site – which significantly simplifies and speeds up the service process. The device has a built-in optical indicator of the operating status.

• Precise measurement: The electrochemical sensor provides accurate and reliable measurements of nitrogen dioxide (NO2) concentration.
• Versatility: The 4-20mA analog output enables integration with various control and alarm systems.
• Easy maintenance: The replaceable sensor facilitates servicing and reduces operating costs.
• High quality: GAZEX detectors are calibrated in their own laboratory accredited in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which guarantees their reliability and measurement accuracy.
• Durable construction: The splash-proof housing protects the device from the effects of adverse environmental conditions.
• Optical signaling: Built-in LEDs indicate the detector's operating status.

Technical specifications (approximate data)

According to the technical documentation, the DG-P0E.NO2/N detector is designed to operate in an ambient temperature of -20°C to +50°C (please check the current data on the manufacturer's website). The calibration period for the electrochemical sensor is typically 6 months from the date of manufacture or according to the manufacturer's recommendations – it is worth checking the specification of the specific MS-P0E.NO2/N sensor model. It is important to remember the potential sensitivity of the sensor to other gases (so-called cross-sensitivity) – detailed information on this subject can be found in the GAZEX technical documentation and in cross-sensitivity tables for electrochemical sensors (e.g., the influence of CO, H2S, SO2).

The DG-P0E.NO2/N detector is a reliable tool for monitoring air quality and ensuring safety in workplaces exposed to nitrogen dioxide. Its versatility, ease of use and high quality of workmanship make it an ideal choice for both professional installers and end-users who care about their own safety and that of their employees.
