Explosion-proof Process Analyzers

In many cases, the highly conformed IP66-NEMA4-rated housings of process analyzers are sufficient when installed outside the hazardous area. But in locations classified as hazardous areas, certified explosion-proof systems are required.

For those circumstances, the ADI 2045TI Ex Proof Analyzer, fulfilling EU ATEX directives and certified for Zone-1 and Zone-2 areas, is available in a stainless-steel explosion-proof version for titration and photometric applications, and the 2060 The NIR-Ex Analyzer or 2060 The NIR-REx Analyzer for spectroscopic applications.

For hazardous environments, Metrohm Process Analytics engineers and supplies custom-made solutions for any type of environment. Therefore, no manual sampling is necessary, which leads to a safer working environment (e.g., exposure to Cl₂, exothermic epoxidation, high temperature/pressure, autopolymerization, and more).

Our custom-made solutions can vary from sample conditioning systems to complete shelters including ATEX-certified systems for Zone 1 and Zone 2 environments. Metrohm Process Analytics ensures the integrity of the installed systems throughout the life span of such installations by following the corresponding directive: EN-IEC60079-17 to safeguard any type of process.

Metrohm Process Analytics’ certified explosion-proof analyzers consist of a pressurized stainless-steel cabinet together with intrinsic safety electronic devices. This ensures that the integrity of the ATEX certification is always met thereby allowing routine maintenance (wet part section only) to be conducted without the use of “hot work” permit (e.g., Production line does not need to be stopped for maintenance).
