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

Gas detectors – reliable hydrogen sulfide concentration monitoring

The DG-5E/M gas detector is an advanced device designed for continuous monitoring of hydrogen sulfide (H2S) presence in various spaces. Its task is to measure the gas concentration in the environment and signal exceeding permissible norms. The detector works with the Digital Gas Detection System, transmitting alarm information to the supervisory module via the RS-485 network. The device finds application in industrial plants, logistics centers, public utility facilities, and everywhere where there is a risk of toxic gas emissions.

Construction and principle of operation

The DG-5E/M detector uses an electrochemical sensor for precise measurement of hydrogen sulfide concentration. The replaceable sensor module facilitates maintenance, simplifies calibration, and reduces operating costs. The built-in microprocessor ensures stable operation, and the thermal compensation system minimizes the impact of temperature changes on measurement accuracy. Alarm signaling is carried out using LEDs, and the alarm status history allows for event analysis. The detector housing made of high-impact ABS (IP44) protects it from moisture and mechanical damage. Two cable glands facilitate connecting subsequent detectors in the system.

Applications and benefits

• Safety: Continuous monitoring of H2S concentration allows for a quick response in the event of exceeding permissible norms, protecting personnel and the environment.
• Reliability: Replaceable sensor module and built-in microprocessor ensure stable and precise operation of the device.
• Flexibility: The ability to configure detector settings using the dedicated "DETnet View" software allows you to adapt it to specific application needs.
• Ease of integration: RS-485 communication with the MODBUS RTU protocol enables easy integration with existing control and monitoring systems.
• Convenience: Removable screwless terminals facilitate connection of wires, and a splash-proof housing provides protection against moisture.
• Calibration: All detectors are factory calibrated in their own GAZEX Calibrating Laboratory accredited according to PN-EN ISO/IEC 17025 (PCA accreditation no. AP150).
• Specialized application: Calibration for a range below 100 ppm makes the detector particularly useful in applications requiring high sensitivity of hydrogen sulfide measurement.

The device should not be used in places exposed to the explosion hazard of gases, vapors or dusts – it is a detector of conventional construction.
