The Gascard is a high performance, highly stable, OEM infrared gas sensor, designed for integrating into a wide range of gas analysers, where high levels of repeatability and reliability are required. Gascard instruments can also be used as 'stand-alone' sensors, where an instrument housings are not required. Gascards are microprocessor controlled and offer many output and expansion facility options. The 'fail to safety' attributes of our infrared gas sensors offer distict safety advantages over other technologies.
