Testo 300+ Flue Gas Analyser Ultra Smart Kit

The Testo 300+ Flue Gas Analyser Ultra Smart Kit gives heating engineers a fast and reliable way to test domestic heating systems. It delivers clear readings for oxygen and carbon monoxide while also supporting optional nitric oxide checks. In addition, the large touchscreen makes live measurements simple to view during service work. The strong battery life also helps engineers work for longer without interruption.

Built for demanding daily use, the Testo 300+ Flue Gas Analyser Ultra Smart Kit combines smart controls with dependable sensor performance. Bluetooth support allows up to four probes to connect at once, so users can collect more data in less time. As a result, testing becomes quicker and more efficient across different gas appliances and heating systems.

Smart Connectivity and Reporting

Wireless connectivity gives engineers greater flexibility when working in tight spaces or busy plant rooms. The integrated WLAN and Bluetooth functions support fast data transfer and remote monitoring through the Testo Smart App. Users can also create reports directly from the analyser, helping speed up paperwork after testing is complete.

A bright 5-inch touchscreen provides easy navigation and clear viewing even during long jobs. Multiple readings can appear on screen together, which improves monitoring during combustion analysis and pressure checks. Furthermore, onboard calculations help users assess combustion ratio, efficiency and flue gas loss without needing separate tools.

Built for Daily Heating Work

The Testo 300+ Flue Gas Analyser Ultra Smart Kit is supplied with a wide range of accessories for complete heating analysis work. Pipe thermometers, a Bluetooth manometer and a gas leak detector are all included in the kit. This allows engineers to carry out temperature, pressure and leak testing with one practical solution.

Designed for long-term performance, the analyser uses durable sensors with a five-year lifespan and a scratch-resistant display with protective film. The compact carry case also helps keep equipment protected during transport between jobs. Because of its reliable performance and easy operation, the Testo 300+ Flue Gas Analyser Ultra Smart Kit suits both servicing and fault-finding applications.
