Methane measuring detector DEX-P1R2/N Gazex Vietnam

 

 

Product Overview

GAZEX DEX-P1R2/N is an advanced ATEX-certified infrared methane gas detector designed for continuous monitoring of combustible gas concentrations in hazardous industrial environments.

The detector belongs to the DEX/P (Ex) series, developed for measuring explosive and toxic gases with a standard 4–20 mA analog output, enabling seamless integration with industrial gas detection and automation systems.

With high reliability, explosion-proof construction, and infrared sensing technology, the DEX-P1R2/N is an ideal solution for industries requiring accurate methane detection and enhanced operational safety.


Advanced Infrared Methane Detection Technology

The DEX-P1R2/N utilizes an infrared (IR) sensor module MS-1R2/N specifically designed for methane (CH₄) detection. Unlike catalytic sensors, infrared technology offers:

  • Higher long-term stability
  • Reduced maintenance requirements
  • Improved resistance to sensor poisoning
  • Accurate gas concentration measurement

The detector continuously measures methane concentration within the range of 5–50% LEL, with standard alarm thresholds at 10/30/50% LEL.
