At the event, Mems AG will highlight its two flagship products:

• gasQS® static – A stationary gas quality analyzer for continuous, real-time measurement of H₂ purity, H₂ content in natural gas, H₂ in ammonia, and biogas applications such as CH₄ in CO₂. With ATEX / IECEx certification, high chemical resistance, and a measurement range up to 100 mol% H₂, it offers unmatched stability, fast response times, and no moving parts.
• gasQS® flonic – A compact sensor delivering multiple gas quality metrics including calorific value (HHV/LHV), Wobbe Index, density, compressibility factors, methane number, and H₂ content up to 50%. Certified to ATEX / IECEx and OIML R140, the flonic is approved for custody transfer and billing applications, offering high accuracy, robustness, and easy integration via Modbus.

“Our solutions enable precise, real-time gas quality monitoring – from pure hydrogen to complex gas blends – making the energy transition measurable and reliable,” said Marco Siragna, Co-CEO at Mems AG. “We look forward to engaging with industry partners in Hamburg and showcasing how our technology supports both hydrogen innovation and operational excellence.”
