If you're an HVAC technician, you know combustion testing isn't optional—it's essential for safety and efficiency. The Fieldpiece CAT85K2 combustion analyzer gives you the professional-grade readings you need, right when you need them, without the hassle of carrying multiple tools.
This analyzer measures oxygen (O2), carbon monoxide (CO), flue temperature, and calculates combustion efficiency automatically. Instead of juggling separate meters and doing the math yourself, you get all the critical data displayed clearly on one screen. The live draft measurement shows you exactly how well the system is breathing, catching ventilation issues before they become expensive callbacks.
The integrated manometer eliminates the need to carry a separate pressure gauge. Whether you're checking gas pressure, measuring static pressure in ductwork, or verifying draft readings, you've got the tool built right in. One less thing to pack, one less thing to forget.
Here's where this analyzer really shines: the built-in printer. Instead of scribbling numbers on paperwork or taking photos of the screen, you can hand customers a professional printout of combustion results before you leave. It builds trust, documents your work, and looks a whole lot more professional than handwritten notes.
Fieldpiece designed this for technicians who work in basements, crawlspaces, and rooftops—not climate-controlled labs. The rugged housing stands up to job site abuse, and the intuitive interface means you're not digging through menus while a customer watches over your shoulder.
For HVAC pros who take combustion testing seriously, this analyzer is the kind of tool that pays for itself in time saved and callbacks avoided.
