If you manufacture portable or fixed industrial gas detection monitors, stack gas analysers or environmental monitoring instruments, Alphasense has the solution for your needs.

With a broad portfolio of products detecting all the common and many of the exotic gases, Alphasense has established a reputation as the most reliable source for a wide range of gas sensor technologies.

The Alphasense range includes electrochemical sensors which detect Oxygen and toxic gases, infrared sensors for Carbon Dioxide and hydrocarbons, PID for the detection of Volatile Organic Compounds (VOCs) and fully certified pellistors for combustible gas detection.
