testo 320 Pro - Flue gas analyser kit with O₂ and CO sensors up to 10,000 ppm, NO upgradeable

The testo 320 Kit 3 is designed specifically for HVAC/R professionals who need a standard flue gas analyser with an extended CO measuring range. At the heart of the kit is the testo 320 with an O₂ sensor and a CO/H₂ sensor offering a CO range up to 10,000 ppm. This makes it suitable for standard combustion checks on a wide range of heating systems, including applications where higher CO concentrations may be encountered. The 5.5-inch IPS touchscreen and app-style interface give a clear overview of all key parameters such as O₂, CO, efficiency (η), flue gas losses, draught and flue gas temperature, while guided workflows allow fast navigation and minimise operating errors. As with all testo 320 kits, parallel measurements allow several values to be recorded simultaneously, increasing efficiency during daily service calls. Kit 3 includes a compact basic flue gas probe, a carrying bag and replacement particle filters, giving technicians a robust, practical solution for everyday use. With integrated Bluetooth and testo Smart App integration, the analyser connects to up to four wireless probes and to testo Smart Connect for centralised data management across instruments, jobs and sites. Key benefits: • Large 5.5" touchscreen to view all your data clearly in real time. • Intuitive app-style interface with step-by-step instructions for simple, fast navigation. • CO sensor up to 10,000 ppm for an extended measuring range. • NO upgradeable thanks to the optional NO sensor. • Connection to the testo Smart App to control measurements, use a second screen and quickly generate reports on site. • Parallel measurements to collect several values at the same time and save time every day.
