Testo 300+ Flue Gas Analyser Smart Heat Pump Kit
The Testo 300+ Flue Gas Analyser Smart Heat Pump Kit gives heating engineers a fast and reliable way to test domestic boilers and heat pumps. It supports smart wireless measurements and delivers accurate readings during servicing work. The large touchscreen and guided menu system also help reduce setup time while improving workflow on site.
Built for demanding daily use, the Testo 300+ Flue Gas Analyser Smart Heat Pump Kit combines flue gas analysis with wireless temperature and pressure testing. Bluetooth connectivity allows up to four probes to connect at once, helping engineers monitor several readings together. In addition, the analyser supports WLAN report generation for faster customer documentation.
Smart Heating System Measurements
Engineers can use the kit to measure oxygen, carbon monoxide, pressure and temperature across heating systems. The supplied digital manifold, Bluetooth thermometers and manometer support testing on monobloc and split heat pump systems. As a result, users can complete detailed service checks with fewer separate tools.
A bright 5-inch touchscreen makes readings easy to view even in busy plant rooms or domestic spaces. Graph display functions help track live changes during testing, while the scratch-resistant screen film adds extra durability. The Testo Smart App also enables remote viewing of results when working away from the analyser.
Designed for Daily Field Work
The Testo 300+ Flue Gas Analyser Smart Heat Pump Kit includes long-life sensors designed for up to five years of use. Battery operation of up to 10 hours supports extended servicing jobs without constant charging. Furthermore, the compact design and supplied carry case make transport between jobs simple.
Wireless communication and instant report generation help improve efficiency during inspections and maintenance work. The analyser also performs onboard calculations for combustion efficiency, CO₂ levels and flue gas loss. With durable construction and advanced sensor performance, this kit supports accurate testing across a wide range of heating applications.
