Gas detector DG-4E/N2-Nstd ammonia (selective - wastewater treatment plants), calibration on request <100ppm, electrochemical sensor DG-4E/N2-NSTD

Ammonia detection in wastewater treatment plants – reliability and precision

This gas detector is designed for continuous monitoring of ammonia concentration, especially in environments requiring high selectivity, such as wastewater treatment plants. The DG-4E/N2-Nstd device utilizes an electrochemical sensor, providing accurate measurements and a fast response to changes in gas concentration. Thanks to the possibility of custom calibration (up to 100 ppm), the detector is ideally suited to the specific needs of a given facility.

Construction and application in gas detection systems

The DG-4E/N2-Nstd detector is an element of a hazard signaling system that warns against exceeding permissible ammonia levels. It is a threshold device, meaning it reacts to exceeding previously defined alarm levels. It can work with various control modules (e.g., MD-1.A/T, MDP-1.A/T), enabling integration with existing safety systems. The detector's design allows for surface mounting, and the splash-proof housing (IP44) ensures resistance to conditions prevailing in industrial halls and wastewater treatment plants.

Key features and benefits for installers and users

• Replaceable sensor: Allows for quick replacement of a damaged element or adaptation to other gases, minimizing downtime and operating costs.
• Two alarm thresholds: Allow setting different warning levels, tailored to the specifics of a given process or room.
• Built-in optical signaling: A multi-colored LED indicates the device's operating status and exceeding alarm thresholds – immediate feedback on potential hazards.
• Thermal compensation: Ensures stable and reliable measurements even at variable ambient temperatures.
• Calibration in an accredited laboratory: Guarantee of measurement accuracy confirmed by PCA certificate No. AP150 in accordance with PN-EN ISO/IEC 17025 standard.
• Easy installation and operation: Modular design and simple connections facilitate device installation and servicing.
• Designed for cooperation with control modules: Provides flexibility in building complex gas detection systems.

The DG-4E/N2-Nstd detector is a solid solution for ensuring safety in places where there is a risk of ammonia leakage – from wastewater treatment plants to industrial plants. Its precision, reliability and ease of use make it an ideal choice for both professional installers and end-users who care about the safety of their employees and the environment.
