Our Products

Two complementary product lines of gas quality sensor & measurement systems
– Precision made in Switzerland, delivered globally.

gasQS™ static

Reliable inline gas measurement for stable process conditions. A maintenance-free gas sensor with exceptional accuracy and long-term stability.

gasQS™ flonic

Dynamic gas quality measurement for varying compositions - also a cost-effective alternative to gas chromatographs for real-time process monitoring.

Applications

Wherever precise gas quality measurement matters - from biogas plants and gas engines to hydrogen distribution and smart grid gas applications.

Gas Distribution

Real-time monitoring of gas composition for efficient grid injection, gas billing, and H₂-readiness in modern distribution networks.

Gas Engines & Turbines

Gas engine and turbine efficiency depends on dynamically changing gas quality, and gasQS™ flonic & gasQS™ static provide fast, precise real-time data to enable automatic optimization of operating parameters.

Biogas plants

Precise control of methane content – for optimized plant operation, early process detection, and safe injection into the gas grid.

Ammonia Cracking

From ammonia back to hydrogen – monitored in real-time, with no calibration required.

H₂ Purity

Reliable, continuous monitoring of hydrogen purity - ensuring safe operation, maximum process efficiency, and compliance with strict purity requirements in electrolysis, fuel cell, and power-to-gas systems.

Engineering Services

From concept to market readiness - we leverage our expertise in electronics development, embedded firmware, and measurement technology to guide your product to series production in a targeted and efficient manner.

Electronics

Electronics and mechanical engineering using CAD - from the first prototype to the production-ready product.

Firmware & Software

Custom firmware and software solutions - precisely tailored to your specific hardware and application requirements.

Measuring technology

Precise measurement solutions through the combined use of microsystems and conventional sensor technology - for demanding measurement tasks in industrial environments.

Why MEMS

Over 20 years of experience in gas measurement technology – our devices are designed and tested for reliable, high-precision continuous operation in demanding industrial environments.

Real-time response

Short T90 response time enables real-time monitoring and control.

Robust Design

Designed for the rigors of everyday industrial use – reliable and stable over the long term, even under demanding process conditions.

Reliable

Maintenance-free, with no carrier gases and no moving parts – our gas sensors deliver stable, long-term measurement values with absolutely no ongoing operating costs.

“For years, our gasQS flonic measuring devices have impressed us with their outstanding performance and reliability.”

E.G.O.

“We have two gasQS measuring devices in operation, and they have been performing perfectly since the beginning.” –

Florian Hupka

“We have been using gasQS measuring devices from Mems in our gas mixing systems for several years to determine the properties of various gas mixtures. Their easy installation allows for quick commissioning. The accurate and long-term stable measurements provide our customers with excellent information about hydrogen content, calorific value, or heating value in the gas mixture. Currently, we frequently use the gasQS static for customer projects involving propane/air and natural gas/hydrogen mixtures. The support and service from Mems are outstanding, and we are very satisfied.”
