Hydrogen Gas Detector – Reliable Protection and Precise Measurement

This hydrogen gas detector, designed to detect dangerous concentrations of hydrogen in enclosed spaces, combines advanced technology with a robust construction. The device signals exceeding two alarm thresholds, ensuring a quick response in case of danger. It is a key element of safety systems in areas where there is a risk of explosion or fire related to the presence of hydrogen.

Construction and Application

The DEX-7E/N-Nstd detector is an explosion-proof device, meeting the requirements of the ATEX Directive, allowing its safe use in areas at risk of explosion of gases or flammable vapors (IIA, IIB, IIC). F4-C construction with a brass housing ensures durability and corrosion resistance. The electrochemical sensor guarantees high selectivity of hydrogen measurement, minimizing the risk of false alarms. The device is powered by the system and designed to work with various GAZEX control modules (MD-1.A/T, MD-1, MD-2, MD-4, MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16 and MDD-1, MDD-1/T, MDD-1x/T).

Advantages and Benefits

• High selectivity: The electrochemical sensor provides a precise measurement of hydrogen concentration and minimizes the risk of false alarms.

• Durable construction: The brass housing protects the device from mechanical damage and external factors.

• ATEX compliance: Safe use in explosion-prone areas.

• Calibration on request: Adaptation of the device to specific user needs.

• Modularity: Compatibility with a wide range of GAZEX control modules facilitates integration with existing safety systems.

• Replaceable sensor modules: Allow easy replacement and calibration of the sensor without the need to replace the entire detector – this reduces operating costs.

• Patterning: Detectors are patterned in their own GAZEX Accredited Calibration Laboratory in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No. AP150), which guarantees measurement accuracy.

• Environmental resistance: Availability of versions with a brass (nickel-plated) or stainless steel (316L) housing for use in aggressive environments.

This detector finds application in many industries – from the chemical and petrochemical industries to research laboratories and battery warehouses. Its reliability and measurement accuracy make it an ideal choice for anyone who cares about safety in workplaces exposed to hydrogen.
