Gas detector for monitoring explosive and toxic hazards

The DEX-3R/N-Nstd gas detector is a reliable device designed for continuous monitoring of organic compounds in the air. It utilizes an optical IR (Infra-Red) sensor, which ensures high selectivity and measurement accuracy. It is a key element of safety systems in areas where there is a risk of explosion or poisoning by gases. The device signals exceeding two alarm thresholds (A1, A2), ensuring a quick response to potential hazards.

The detector is particularly useful in the chemical, petrochemical, and mining industries, as well as in warehouses and other facilities where organic vapor is present. The brass housing provides durability and corrosion resistance, and the explosion-proof design allows for safe use in potentially explosive areas (IIA, IIB, IIC; T1-T6). Calibration to order guarantees measurement accuracy tailored to the specific needs of the user.

Design and application

Detectors of the DEX/F series are designed to work with various types of 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 addressable units MDD-1, MDD-1/T and MDD-1x/T. The replaceable sensor module facilitates maintenance and reduces operating costs – allowing for quick sensor replacement without replacing the entire detector. Built-in temperature compensation and linear compensation algorithms ensure stable and reliable readings even in changing environmental conditions.

The device meets the requirements of the ATEX Directive 2014/34/EU and has a certificate of conformity with safety standards. Therefore, it can be used in potentially explosive atmospheres without fear of ignition. The detector is calibrated in the GAZEX Calibrating Laboratory accredited in accordance with PN-EN ISO/IEC 17025 (PCA No. AP150), which confirms its high quality and measurement accuracy.
