Gas detector DG-4E2/M-Nstd ammonia (selective - wastewater treatment plants), calibration on request <100ppm, electrochemical sensor DG-4E2/M-NSTD

Ammonia detection in wastewater treatment plants – reliable protection and control

The DG-4E2/M-Nstd gas detector is an advanced device designed for continuous monitoring of ammonia concentration in areas where there is a risk of its emission, especially in wastewater treatment plants. Thanks to the selective electrochemical sensor, the detector provides precise measurements even in environments with varying humidity and temperature. The device is a key element of the gas detection system, informing about exceeding permissible norms and enabling a quick response in case of a hazard.

Construction and operating principle

The DG-4E2/M-Nstd detector is based on digital technology, which guarantees the stability and reliability of measurements. Communication is via the RS-485 port with the MODBUS RTU protocol, which facilitates integration with existing monitoring and control systems. A replaceable sensor module allows for easy maintenance and calibration of the device, minimizing operating costs. The built-in microprocessor is responsible for thermal compensation and recording the history of alarm states, which facilitates event analysis and process optimization.

Application and benefits

• Health and life protection: Quick detection of ammonia allows avoiding hazards associated with its toxic effects on the human body.
• Process safety: Controlling the ammonia concentration in wastewater treatment plants allows for optimization of biological processes and prevention of failures.
• Compliance with standards: The device meets stringent safety standards, ensuring compliance with applicable regulations.
• Easy installation and operation: Splash-proof housing (IP44) and two cable glands facilitate mounting the detector in harsh industrial conditions. Removable screwless terminals simplify the connection of FTP cables.
• Low operating costs: A replaceable sensor module and the ability to configure settings using the dedicated "DETnet View" software reduce maintenance costs.
• High measurement accuracy: Calibration on a range up to 100 ppm ensures precise measurement of ammonia concentration, which is crucial for effective monitoring of technological processes.
• Alarm signaling: The built-in LED optical signaling informs about exceeding permissible ammonia concentration values, enabling a quick response to the hazard.

The device is calibrated in its own GAZEX Accredited Calibration Laboratory according to PN-EN ISO/IEC 17025 (PCA accreditation No. AP150), which guarantees the reliability of measurements. The DG-4E2/M-Nstd detector is an investment in safety and work efficiency in wastewater treatment plants and other industrial facilities exposed to ammonia emissions.
