About Us

Gas Sensor Technology

Gas Sensing Solutions Ltd. (GSS) is a pioneer in the use of solid-state mid-infrared semiconductor devices for gas sensing applications. For more than a decade, we have been delivering state-of-the-art gas sensors for high-performance gas measurement applications.

Headquartered in the UK, our mid-infrared LEDs and companion photodetectors are designed, developed and manufactured in-house on ultra-high vacuum systems by molecular beam epitaxy (MBE) and used in all our patented NDIR diffusion gas sensors.

What We Do

GSS designs and manufactures a wide range of solid-state NDIR gas sensors, providing innovative measurement solutions for the world’s leading OEMs where low power, high accuracy and high-speed measuring capability are required. 

GSS is a market leader in ultra-low power CO₂ sensors, enabling a whole new class of interior air quality monitoring equipment capable of running for years on battery power alone.

Leveraging our expertise in high-speed optical design, we have created gas sensors that are capable of measuring levels of CO2 and Methane gas in real-time, with unparalleled levels of accuracy.

We are a trusted partner for medical and life sciences applications where lives are on the line.

To provide best-in-class service to leading OEMs requires an organisation that delivers time and time again. Our ISO-9001 certified processes provide a foundation for ensuring that we earn your trust year after year.
