Fyrite® Pro
Residential Combustion Gas Analyzer

  The Fyrite Pro is perfect for HVAC professionals who service and evaluate residential furnaces and appliances.



The Fyrite Pro is a residential combustion analyzer that saves you both time and money by offering measurement precision you can rely on at an affordable price. The Fyrite Pro enables the service technician to verify the performance and adjust residential furnaces and appliances quickly and easily, enabling you to increase your overall service productivity. 

The top-of-the-line Fyrite Pro 125 is packed full of features, providing the service technician the necessary information to conduct a combustion test, CO safety test, draft test and differential pressure test using just one instrument. The compact and ergonomically designed Fyrite Pro provides quick and accurate measurement of oxygen (O2), ambient and combustion air temperatures, stack temperature, carbon monoxide (CO), draft, and differential pressure. Calculations include: combustion efficiency, excess  air, carbon dioxide (CO2), and CO air free. 

The Fyrite Pro comes complete with a carrying case, probe & hose assembly and batteries. An IrDA wireless printer that comes standard or as an optional item (depending on model ordered) provides documentation of the test results.
