Gas detector DG-4E/MR ammonia, 500/800 ppm, electrochemical sensor

Gas detectors – reliable safety in any environment

The DG-4E/MR gas detector is an advanced device designed for continuous monitoring of ammonia presence in the air. It is used to precisely measure the concentration of this gas in the range of 500-800 ppm, utilizing a reliable electrochemical sensor. This detector finds application in industrial plants, logistics centers, and public facilities, where ensuring safety and rapid response to potential hazards is crucial.

Functionality and application

The DG-4E/MR device is not only precise measurement but also an effective alarm system. In the event of exceeding defined concentration thresholds of ammonia, the detector activates a built-in optical signaling and activates low-voltage relays. Additionally, alarm information is sent to the digital supervisory module via the RS-485 interface, enabling central monitoring and a quick response to the threat. Thanks to the replaceable sensor module, the maintenance and calibration of the device are simple and economical.

Advantages of the DG-4E/MR detector

• High measurement accuracy: The electrochemical sensor provides accurate and reliable measurement results of ammonia concentration in the range of 500-800 ppm.
• Fast response: The detector's short response time allows for quick detection of a dangerous increase in gas concentration.
• Versatility: Ability to cooperate with the GAZEX Digital Gas Detection System and easy integration with existing monitoring systems.
• Easy maintenance: Replaceable sensor module simplifies the calibration process and reduces operating costs.
• RS-485 communication: Ensures reliable data transmission to the central supervision system using the MODBUS RTU protocol.
• Two alarm thresholds: Allow flexible adaptation to specific application requirements and ensure an appropriate level of warning.
• Built-in relays: Two relays with NO/NC contacts allow direct control of external devices, such as acoustic signaling devices or ventilation systems.
• Solid construction: The device made of high-quality materials ensures durability and reliable operation even in harsh industrial conditions.

The DG-4E/MR detector is an ideal solution for installers looking for a reliable and easy-to-use ammonia detection system, as well as for end-users who care about safety in their facilities. However, remember that this is a device of conventional construction and should not be used in places threatened by the explosion of gases or dust. All GAZEX detectors are calibrated in their own laboratory accredited according to the PN-EN ISO/IEC 17025 standard, which guarantees the accuracy and reliability of measurements.
