Gas detectors – reliable safety in hazardous areas

The DEX-3K/N-Nstd gas detector is an advanced device designed for continuous monitoring of explosive, toxic gases or liquid vapors in enclosed spaces. Its construction, based on the principle of a catalytic sensor, allows for precise detection of organic compounds. The device signals exceeding defined alarm thresholds (A1 and A2), ensuring a quick response in case of danger. Thanks to the possibility of custom calibration, the detector can be adapted to specific needs and working conditions.

Construction and application

The DEX-3K/N-Nstd detector is distinguished by a solid explosion-proof construction, which allows for its safe use in hazardous areas (1 or 2) of various temperature classes (T1-T6) and explosion groups (IIA, IIB, IIC). F4-B execution with a brass housing provides high resistance to corrosion and mechanical damage. The device is designed to cooperate with MD…. type alarm modules. The alarm signaling is realized via bistable outputs.

Key features and benefits

• Safety confirmed by ATEX certificate: the detector meets the requirements of Directive 2014/34/UE, guaranteeing safety of use in potentially explosive atmospheres.
• Replaceable sensor modules: allow for easy replacement and calibration of the sensor without the need to replace the entire device, reducing operating costs. Built-in thermal and linear compensation algorithms ensure measurement accuracy.
• Modularity and simple installation: the detector's construction facilitates design and installation, minimizing system downtime.
• High measurement accuracy: the catalytic sensor provides precise detection of organic compounds, which is crucial for ensuring safety.
• Calibration in an accredited laboratory: all GAZEX detectors are calibrated in their own Calibrating Laboratory operating in accordance with PN-EN ISO/IEC 17025 (PCA accreditation no. AP150), which guarantees the reliability of measurement results.
• Durable construction: the brass housing provides resistance to harsh environmental conditions and long-term device reliability.
• Custom calibration option: allows you to adjust the detector's sensitivity to specific application needs.

The device finds application in many industries, such as: chemical, petrochemical, mining, energy and everywhere where there is a risk of explosive or toxic gases. This detector is ideal for both professional gas system installers and end-users who care about safety in their facilities.
