Testo 310 Flue Gas Analyser
The Testo 310 Flue Gas Analyser gives heating engineers a fast and reliable way to complete combustion testing and boiler servicing. Its compact body and simple controls help users work with ease in busy environments. In addition, the bright graphic display presents readings clearly, which helps reduce mistakes during testing.
Designed for domestic heating systems, the analyser measures oxygen, carbon monoxide, flue gas temperature and draught with dependable accuracy. The rechargeable battery supports long working hours and charges through USB-C for added convenience. Furthermore, the quick 30 second sensor zeroing process helps engineers save time on site.
Fast Testing and Simple Operation
Built-in magnets allow the Testo 310 Flue Gas Analyser to attach securely to boiler casings for hands-free work. The lightweight construction and kink-resistant hose also improve comfort during daily servicing tasks. As a result, engineers can move around freely while keeping measurements visible at all times.
Bluetooth connectivity works with the Testo Smart App for digital reporting and easy customer record management. Reports can be stored and transferred directly from the analyser to a compatible mobile device. Optional wireless printer support also makes it easier to provide printed results immediately after testing.
Reliable Measurements for Daily Servicing
The Testo 310 Flue Gas Analyser supports extra measurements when used with compatible Testo Smart Probes. This allows users to check gas flow pressure, flow temperature and return temperature from one connected system. Consequently, engineers can complete a wider range of heating checks with fewer tools.
Strong measurement performance and dependable sensor response make this analyser suitable for commissioning, servicing and safety inspections. The durable housing withstands regular site use while the replaceable probe filter helps lower maintenance costs. With support for BS7967 and EN50379 standards, the analyser provides confidence during professional testing work.
