Gas detector DEX-22/NL carbon monoxide, 20/100ppm (s15), execution F4-C, p-p sensor, brass housing

Carbon Monoxide Gas Detector – Reliable Safety in Any Environment

The DEX-22/NL gas detector is an advanced device designed for continuous monitoring of carbon monoxide (CO) concentration in enclosed spaces. Equipped with a precise semiconductor sensor, the detector signals exceeding two established alarm thresholds, ensuring a quick response in case of danger. The device is particularly useful wherever there is a risk of dangerous CO concentrations, such as boiler rooms, furnaces, fireplaces, workshops, or garages.

Design and Application

The DEX-22/NL detector has been designed with demanding working conditions in mind. A solid brass housing guarantees high resistance to mechanical damage and corrosion, and the explosion-proof design (F4-C marking) allows for its safe use in potentially explosive areas. Therefore, the detector finds application not only in residential and public buildings but also in industry – wherever reliable protection against the effects of carbon monoxide is required. The device is powered from the system, eliminating the need for frequent battery changes.

Key Features and Benefits

• High measurement accuracy: The semiconductor sensor ensures accurate detection of carbon monoxide in the range of 20-100 ppm.
• Two-stage alarm: Two alarm thresholds (A1 and A2) allow for a quick response to changing conditions and adaptation of appropriate safety measures.
• Durable construction: The brass housing protects the device against mechanical damage and external factors.
• Explosion-proof design: The detector can be used in areas at risk of explosion of gases or flammable vapors (group IIA, IIB or IIC).
• ATEX compliance: The device meets the requirements of Directive 2014/34/EU, which guarantees its safety and reliability.
• Replaceable sensor module: Allows easy replacement of the sensor without the need for calibration of the device on-site – reduces operating costs.
• Thermal compensation: The built-in thermal compensation circuit ensures stable measurements even at variable ambient temperatures.
• Calibration: All detectors are factory calibrated in the accredited GAZEX Calibration Laboratory (PCA accreditation No. AP150), which ensures high measurement accuracy.
• Compact dimensions: Dimensions of 105 x 103 x 54 mm facilitate mounting of the detector even in hard-to-reach places.

Thanks to these features, the DEX-22/NL detector is a comprehensive solution for people looking for a reliable and precise carbon monoxide concentration monitoring system. Both installers and end-users will appreciate the ease of installation and the long-lasting and trouble-free operation of the device.
