Pyreos’ range of high performance NDIR gas detectors provide new possibilities to accurately and continuously monitor critical levels of anaesthetic gases and simultaneously monitor patient ventilation and wellbeing. Our products are the fastest pyroelectric or thermopile technology allowing higher resolution and ultra low power consumption. The world-first digital SMD pyroelectric device is the smallest pyroelectric sensor available and they are physically robust. We cover most major anaesthetic gases including Carbon Dioxide, Nitrous Oxide, Enflurane, Halothane, Isoflurane, Desflurane and Sevoflurane. We also have a veterinary product. We will be happy to discuss your requirements and help match the products to your gas selection.

New – upgraded analogue quad range with 4x larger pixel area

Pyreos is now sampling our new quad range which carries 4 x 1mm2 pixels.  This provides much higher SNR and the product is mechanically vastly simpler and more robust than competing products.  Datasheet Download.   As well as the list of quads in the table below, a new, more extensive list of filter combinations is available.  The quad product range is expanding fast so if we do not list the you need then please contact us.
