This company has expanded its 993X series of gas analyzers – including both 993X and 9933 models – with new explosion proof (Ex d) enclosures certified for ATEX and IECEx Zone 1 hazardous locations. The new design enables reliable analyzer 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.

The 993X series primarily uses ultraviolet (UV) spectroscopy to provide continuous measurement of sulfur compounds and other key components in natural gas and biomethane streams, including hydrogen sulfide, carbonyl sulfide, and methyl mercaptan. The analyzers are also widely used in sulfur recovery and removal processes to measure sulfur-containing species such as sulfur dioxide and carbon disulfide, supporting process control, emissions compliance, and product quality. Other technologies can also be integrated to measure the concentrations of hydrogen and carbon dioxide in these end user applications, when required. With the addition of explosion proof certifications, the 993X series offers greater flexibility for operators designing analyzer shelters and hazardous area installations across oil and gas production, processing and renewable gas applications. — Ametek Process Instruments, Pittsburgh, Pa.
