Gas detector DEX-12/N-Nstd methane, calibration on request, F4-C design, p-p sensor, AL housing DEX-12/N-NSTD

Methane detector DEX-12/N – safety and reliability in one device. The DEX-12/N gas detector is an advanced device designed for continuous monitoring of methane concentration in enclosed spaces. It is used to detect dangerous levels of natural gas, providing protection against potential explosive and toxic hazards. The device signals exceeding two alarm thresholds (A1 and A2), set by the manufacturer, allowing for a quick response in the event of a failure or leak. It is a key element of safety systems in gas boiler rooms, industrial plants and other facilities where there is a risk of methane presence.

Design and application

The DEX-12/N detector has been designed with demanding working conditions in mind. It has a solid aluminum (AL) housing and is made in version F4-C, which ensures its reliability and durability. The device complies with ATEX standards, allowing its use in areas at risk of explosion of gases or flammable vapors (groups IIA, IIB or IIC). It uses a semiconductor sensor, which is characterized by high sensitivity and measurement accuracy. The detector is designed to cooperate with MD type alarm modules, which allows integration with existing monitoring and notification systems.

Key features and benefits

• High sensitivity and accuracy: The semiconductor sensor provides accurate measurement of methane concentration, minimizing the risk of false alarms.
• Two-stage alarm: Two alarm thresholds (A1 and A2) allow for a graded response to increasing gas concentration, enabling appropriate action to be taken depending on the degree of hazard.
• Explosion-proof design: Compliance with ATEX standards guarantees safe use in areas at risk of explosion.
• Replaceable sensor: The ability to replace the sensor module facilitates calibration and repair of the device, reducing operating costs.
• Optical signaling: The built-in optical signaling informs about the operating status of the detector and exceeding the alarm thresholds.
• Modularity: Compatibility with MD type alarm modules facilitates integration with existing safety systems.
• Thermal compensation: Built-in thermal compensation algorithms ensure measurement stability under various temperature conditions.
• Calibration: All detectors are calibrated in their own GAZEX Calibrating Laboratory accredited in accordance with PN-EN ISO/IEC 17025.

The DEX-12/N detector is an investment in safety that protects life and property from the effects of natural gas leaks. Its reliability, accuracy and ease of use make it an ideal solution for both professional installers and end users.
