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. 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.
