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

Nitrogen Dioxide Detection – Reliability and Precision in One Device

The DG-P0E.NO2/MR gas detector is an advanced device designed for continuous monitoring of nitrogen dioxide (NO2) concentration in various environments. It utilizes an electrochemical sensor, providing high measurement accuracy in the range of up to 20 ppm. The detector is ideal for use in industrial plants, logistics centers, and public facilities, where air quality control is crucial.

Functionality and Application

The device is an integral part of the GAZEX Digital Gas Detection System, enabling effective control and rapid response in the event of exceeding permissible NO2 concentration levels. Thanks to RS-485 communication with the MODBUS RTU protocol, the detector easily integrates with existing monitoring and control systems. Built-in two relays with NO/NC contacts allow for direct control of alarm devices or ventilation systems. The ability to configure two alarm thresholds or measurement mode provides flexibility to adapt to specific application needs.

Detector Design and Features

The DG-P0E.NO2/MR detector is distinguished by its solid construction and a range of features that facilitate installation, maintenance, and operation:

• Replaceable sensor module: Enables quick replacement of a damaged sensor or calibration without the need to disassemble the entire device – this reduces maintenance costs and minimizes downtime. Modules are compatible with DG/F and DG/P series, increasing component selection flexibility.
• Screwless terminals: Facilitate connection of wires, especially in hard-to-reach places. The removable design allows connection of two FTP cables.
• Two cable glands: Allow connecting subsequent detectors in a "daisy-chain" network, simplifying wiring and reducing installation costs.
• Built-in microprocessor: Ensures stable and reliable operation of the device and thermal compensation of measurements.
• Alarm history: Allows analysis of events and identification of potential problems in the installation.
• Configuration via DETnet View software: Enables easy adaptation of detector settings to individual user needs (available on the manufacturer's website).
• Calibration: All detectors are calibrated in their own GAZEX Calibrating Laboratory accredited in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No. AP150), which guarantees the accuracy and reliability of measurements.

The device is characterized by compact dimensions (110 x 140 x 55 mm) and 24V= power supply, which facilitates integration with existing electrical infrastructure. However, remember that the detector is not intended for use in areas hazardous due to the explosion of gases, vapors or dusts – it is a device of ordinary construction.
