testo 320 - Standard flue gas analyzer with O₂ and CO/H₂ sensors
Standard flue gas analyzer with extended CO/H₂ sensor up to 10,000 ppm. Designed for standard HVAC/R applications where higher CO levels may occur.
- Clear view at a glance – Large 5.5" touchscreen with real-time data
- Streamlined workflows – App-like interface with step-by-step guidance for fast navigation and consistent results
- testo Smart App integration – Remote control, second screen and fast reporting on site
- Centralized data management – Connecting measurements, jobs and devices in one system via testo Smart Connect
- Parallel measurements – Capture multiple values at once for faster daily work
- All-day operation – Long battery life and fast charging for uninterrupted use throughout the working day
The 5.5" IPS touchscreen and app-like interface provide a clear overview of all key parameters such as O₂, CO, efficiency (η), flue gas loss, draught and flue gas temperature, while guided workflows support fast navigation and minimize operating errors. Parallel measurements enable multiple values to be captured at once, increasing efficiency during daily service work.
With integrated Bluetooth and testo Smart App integration, the analyzer connects to up to four wireless probes and to testo Smart Connect for centralized data management across devices, jobs and locations.
