DEX®/P and DG/P stationary toxic, explosive and oxygen gas detectors are designed to detect and signal the presence of gases with harmful or dangerous concentrations to humans in the work and life environment.
Features of stationary DEX®/P and DG/P gas detectors series:
- 4-20 mA analog output,
- DG/P stationary detectors – ordinary, splashproof construction,
- stationary detectors DEX®/P – explosion-proof construction, meets the requirements of the ATEX Directive 94/9 / EC in the area of application II 2 G
- selected models of detectors with an exchangeable catalytic, conductivity, electrochemical or optical sensor (Infra-Red) – selected for the application,
- exchangeable, intelligent sensory modules with built-in algorithms of thermal compensation, linear compensation, calculation of weighted averages, measurement history and signaling exceeding the recommended calibration period.
- modularity, simplicity of connections, no need for calibration at the installation site = extremely simple, quick design and assembly,
- all stationary detectors are calibrated in GAZEX’s own Calibration Laboratory in accordance with PN-EN ISO / IEC 17025.
