The Fyrite® Classic is a tried-and-true instrument for measuring oxygen and carbon dioxide. The Fyrite® Classic is available for O2 or CO2, and each 
gas type of Fyrite® is available in multiple ranges to meet a variety of applications, from combustion analysis to incubators to anesthesiology.

The Fyrite® Classic contains fluid that is specifically designed to absorb O2 or CO2 with minimal cross-sensitivities to other gases, which leads to 
accurate readings. It is easy to test the fluid’s strength and replace it when needed – which means no need to return the unit for service and no 
downtime.
