Gas detector DG-5E/MR-Nstd H2S, calibration on request <100ppm, electrochemical sensor DG-5E/MR-NSTD

Gas detectors – reliable protection against hazards

The DG-5E/MR-Nstd gas detector is an advanced device designed for continuous monitoring of hydrogen sulfide (H2S) concentration in various industrial and public utility environments. Its main task is to detect dangerous gas levels early, allowing for a quick response and minimizing risks to health and property. The device uses an electrochemical sensor, providing high measurement accuracy and reliable operation. Calibration on request, with an alarm threshold below 100 ppm, guarantees adaptation to the specific requirements of a given facility.

Functionality and application

The DG-5E/MR-Nstd detector is part of the Digital Gas Detection System, enabling integration with other devices and a central monitoring system. When the permissible H2S concentration limits are exceeded, the detector activates optical signaling and transmits information to the supervisory module via the RS-485 network with the MODBUS RTU protocol. This allows for quick notification of the appropriate services and preventive measures. The device is used in industrial plants, logistics centers, public utility facilities, and anywhere where there is a risk of toxic hydrogen sulfide emissions.

Construction and user features

The detector is characterized by a solid construction and easy installation. The replaceable sensor module facilitates maintenance, calibration and reduces operating costs. Additionally, the device has:

• RS-485 communication: Enables integration with monitoring and control systems.
• Two alarm thresholds: Allow for precise setting of warning levels.
• Built-in relays: Provide the ability to activate external alarm devices or ventilation systems.
• Semi-automatic addressing: Facilitates configuration in a digital network without the need to open the housing.
• Screwless terminals: Allow for quick and convenient wiring.
• Replaceable sensor: Ensures easy servicing and calibration of the device.
• Optical signaling: Clear indication of the alarm status using LEDs.
• Thermal compensation: Ensures stable measurements under varying temperature conditions.

The device is powered by 24 V= voltage and its dimensions (110 x 140 x 55 mm) allow for easy adaptation to different spaces. Remember that the detector should not be used in places exposed to the explosion of gases, vapors or dust – this device is intended for operation in safe environmental conditions.
