Bacharach Fyrite Intech Combustion Analyzer, O2 Measurement

Great product but still needed upgrade from the manufacturer to detect CO.

This unit doesn't include a NOx filter hence your CO readings will not be accurate ... you have to purchase the filter separate at around $40 more!Don't waste your money on this unit, its not the better deal ... buy a Testo 310 instead ... comes ready use out of the box at a lower price (equipped CO sensor has NOx filter)! The Testo 310 will go toe to toe with Baacarach's more expensive INSIGHT model!
