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 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 a 1000ft wireless range. A wireless printer is also available for jobsites that require documentation printouts.
