AMETEK expands 993X gas analyser series with explosion-proof enclosures
August 2026
Analytical Instrumentation & Environmental Monitoring
AMETEK Process Instruments has expanded its 993X series of gas analysers, including both 993X and 9933 models, with new explosion-proof enclosures certified for ATEX and IECEx Zone 1 hazardous locations. The new design enables reliable analyser installation in applications where purge gas is unavailable or impractical, addressing a common challenge in remote and utility-limited facilities.
The explosion-proof 993X enclosure is rated IP66 and NEMA 4X, allowing outdoor installation and operation in minimally temperature-controlled environments. By eliminating the need for a continuous inert purge gas supply, the design helps reduce installation complexity, operating costs and overall system infrastructure requirements.
“Many customers rely on purge-protected analysers, but those systems are not practical in every Zone 1 location,” says Michael Gaura, senior product manager at AMETEK Process Instruments. “The explosion-proof 993X gives users a robust alternative that maintains measurement performance.”
The 993X series primarily uses ultraviolet (UV) spectroscopy to provide continuous measurement of sulphur compounds and other key components in natural gas and biomethane streams, including hydrogen sulphide, carbonyl sulphide and methyl mercaptan. The analysers are also widely used in sulphur recovery and removal processes to measure sulphur-containing species such as sulphur dioxide and carbon disulphide, supporting process control, emissions compliance and product quality. Other technologies can be integrated to measure concentrations of hydrogen and carbon dioxide in these applications when required.
With the addition of explosion-proof certifications, the 993X series offers greater flexibility for operators designing analyser shelters and hazardous area installations across oil and gas production, processing and renewable gas applications.
