Tough Enough for any Heating Job
The Fieldpiece Combustion Analyzer HC CAT85 provides a hassle-free solution for technicians to get the job done quickly, easily, and safely while improving system efficiency.
Accurate sensors of O2, CO, pressure, and temperature along with powerful trending, provide key insight into equipment performance SensorVault™ technology seals to prolong sensor life.
Live draft pressure measurement maintains accuracy throughout your combustion test Dual manometer ports are also included for convenience.
The combustion probe uses a patent pending HydroCycle™ pump to return condensate back into the flue - no more water trap hassles!
With Wireless Thermal Printer CATPR for jobsite combustion analysis documentation.
Breakthrough Innovations
If you’re tired of emptying water traps, the CAT85’s flue probe Hydrocycle™ Pump automatically separates and returns accumulated water to the flu. Also, the CAT85 offers a built-in manometer so you can carry one less tool.
Simplicity Redefined
A new, high contrast 5.5” touchscreen display makes it easy to view measurements, whether your jobsite is a dimly lit basement or bright rooftop. You can also save customer data with dedicated fields for client information. If you require advanced diagnoses, a live trend report is available with O2, CO and CO2 readings.
Reliable Performance
Along with a four-year sensor warranty, the CAT85 HVAC combustion analyzer also features patent-pending SensorVault™ technology that extends sensor life by sealing the sensors from oxygen in the air during storage. If they need to be swapped out, they are field-replaceable to maximize uptime.
Rugged Construction
Durable construction and rubberized casing make the CAT85 tough enough to tackle any jobsite conditions. The magnetic back also lets you work hands-free and the padded hardline carrying case has multiple inserts for accessories.
Jobsite Documentation
Connect to Job Link® System App to view trends, draft pressure and customer details, all with 1000’ wireless range. A wireless printer is also available for jobsites that require documentation printouts.
