CONTINUOUS GAS ANALYZERS FOR HAZARDOUS AREAS

PRODUCT OVERVIEW

Where safety cannot be compromised, measurement must be flawless. Explosive atmospheres set the highest bar for safety and reliability, and ABB hazardous area gas analyzers are built to meet it.

Our flameproof, certified instruments continuously and accurately measure gas concentrations in Zone 1 and Zone 2 environments, as well as dust monitoring in Zone 22, all while meeting full ATEX and IECEx compliance standards. Selected analyzers are also available with CSA certification for North American markets.

Combining advanced analytical technology with proven measurement reliability, ABB hazardous area analyzers give you the confidence to operate safely even in the most demanding conditions.

KEY BENEFITS

Global certifications, one supplier

ATEX, IECEx, NEPSI, TIIS, EAC, CSA: our hazardous area analyzers are certified for every major regulatory market, eliminating re-certification across petrochemical, chemical, and pharmaceutical facilities worldwide.

Flameproof design for zone 1, 2 & dust zones

Robust, certified solutions like the AO2040-Fidas24 Ex, EL3060, and PFM 20 Ex deliver precise measurement in explosive atmospheres without compromising performance.

Multi-gas analysis in one compact system

Measure up to five components (CO, CO₂, SO₂, NO, H₂) with cross-sensitivity correction in a single flameproof enclosure. Reduce footprint, complexity, and cost.

Proven technology and low maintenance

Analyzer modules from ABB's trusted Advance Optima line, deployed for years in industrial process analytics. Automatic calibration, self-monitoring, and standard interfaces (Modbus, PROFIBUS) simplify operation and integration.

CERTIFICATIONS

ABB hazardous area analyzers are certified under all major international explosion protection standards and regulations. These certifications ensure operational safety, regulatory compliance, and global market acceptance across multiple jurisdictions.
