testo 300+ Flue Gas Analyser Advanced Kit

Wireless Smart Probe Connectivity: Connect up to four testo Smart Probes for wireless parallel measurement, so several readings can be taken at the same time during a single service visit. Long-Life CO and O2 Sensors: The CO and O2 sensors are fitted with a 5-year lifespan, which supports lower sensor replacement costs and fewer interruptions to your service schedule. CO Safety Testing Range: The H2-compensated CO sensor measures up to 8,000 ppm, helping engineers identify incomplete combustion and safety risks during boiler servicing. Pipe Temperature and Pressure Kit: Two NTC clamp probes measure pipes from Ø 6 to 35 mm across -40 to +125 °C (±1 °C from -20 to +85 °C), and a hose connection set supports separate gas pressure measurement. Efficiency and Combustion Checks: Calculated values such as CO2, excess air and efficiency make results easier to interpret, supporting burner adjustment and commissioning on domestic and commercial heating systems.
