Gas detector DEX-22/NL-Nstd carbon monoxide, calibration on request, F4-C design, p-p sensor, brass housing DEX-22/NL-NSTD

Carbon monoxide gas detector – reliable safety for installations.

This gas detector, designed to detect carbon monoxide (CO), is a key element of safety systems in gas and industrial installations. The device signals exceeding two alarm thresholds, ensuring a quick response in case of dangerous gas concentration. The DEX-22/NL-Nstd detector is particularly useful in enclosed spaces where the accumulation of CO can pose a serious threat to health and life.

Design and application

The DEX-22/NL-Nstd detector is part of the GAZEX DEX/F series of devices, designed to monitor the presence of explosive gases, toxic gases or oxygen. The F4-C version with a brass housing provides high resistance to corrosion and mechanical damage, which is important in harsh industrial conditions. The semiconductor sensor (p-p) guarantees precise and reliable measurements of carbon monoxide concentration. The device is designed to work with various types of GAZEX control panels (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), which facilitates integration with existing monitoring systems.

Features and benefits

• High reliability: The detector meets the requirements of ATEX Directive 2014/34/EU, confirming its safety and compliance with European standards.
• Durable construction: The brass housing protects the device from mechanical damage and corrosion, ensuring long-term operation even in demanding conditions.
• Precise measurement: The semiconductor sensor provides accurate detection of carbon monoxide in the range of 20–1000 ppm.
• Easy maintenance: The replaceable sensor module allows for quick and easy sensor replacement without the need to calibrate the entire device on site – this translates to minimizing downtime and maintenance costs.
• Versatility: Possibility of use in explosive zones (1 or 2) of various explosiveness classes (IIA, IIB or IIC) and temperature (T1–T6).
• Calibration on request: The possibility of individual detector calibration ensures optimal measurement accuracy for specific working conditions.
• Two-state alarm outputs: Two programmable alarm thresholds (A1 and A2) allow for flexible adaptation of the system's response to changing hazard conditions.

Applications

The DEX-22/NL-Nstd detector finds application in a wide range of facilities and installations:

• Gas boiler rooms
• Heating furnaces
• Car workshops
• Industrial facilities using flammable gases
• Ventilation and air conditioning systems
• Tunnels and underground car parks
• Enclosed spaces with potential carbon monoxide emission hazard

The device is an ideal solution for both professional gas safety system installers and end-users who care about their own safety and the safety of those around them. The detector dimensions (105 x 103 x 54 mm) allow for easy mounting in various locations.
