Gas detector WG-20.EG/A CO+NO2, calibration 30/60/150ppm CO+ 3/6/15ppm NO2, p-p + electrochemical sensor, 12V power supply

Gas detector – reliable protection and control

The WG-20.EG/A gas detector is an advanced device designed for continuous monitoring of carbon monoxide (CO) and nitrogen dioxide (NO2) concentrations in enclosed spaces. It is a key element of safety systems in garages, underground parking lots, vehicle inspection stations, and automotive workshops. The device not only informs about exceeding permissible norms but also enables control of ventilation and exhaust systems, ensuring safe working and usage conditions.

Functionality and application

The WG-20.EG/A detector has been designed with reliability and ease of use in mind. Equipped with a replaceable gas sensor, it allows for quick and economical replacement of the measuring element without the need to calibrate the entire device. Thanks to the built-in microprocessor, the detector ensures stable operation and temperature compensation, as well as an event history to facilitate the analysis of potential hazards. The ability to configure control outputs allows integration with various building automation systems.

• CO and NO2 concentration control: Simultaneous measurement of two harmful gases provides comprehensive protection.
• Calibration: Factory calibrated for ranges of 30/60/150 ppm CO and 3/6/15 ppm NO2 – ready to use immediately after installation.
• Alarm signaling: Built-in optical signaling informs about exceeding permissible gas concentration levels.
• Control outputs: Three relay outputs allow connection to ventilation, exhaust systems or external signaling devices.
• 12V power supply: Enables flexible power supply from various sources, e.g. battery or impulse power supply.
• Solid construction: Splash-proof housing (IP54) ensures resistance to environmental conditions prevailing in garages and workshops.

Construction and installation

The WG-20.EG/A detector is characterized by a compact design, integrating a gas sensor, power supply and control circuits in one housing. Installation is simple and intuitive – just mount the device to the wall or ceiling in a suitable place, connect the power supply and configure the control outputs according to the installation needs. Remember to regularly check the sensor status and replace it according to the manufacturer's recommendations – GAZEX offers an accredited calibration laboratory, which guarantees measurement accuracy throughout the device's operating life. All terminals are removable, which facilitates the connection of multi-strand cable type rope.
