Testo 300 LL Longlife NOx Flue Gas Analyser Printer Kit

The Testo 300 LL NOx Flue Gas Analyser Kit features the most powerful combustion analyser in the Testo range with impressive measurement and calculation capabilities topped off by the addition of a factory-fitted NO sensor. Further accessories include a printer, flue probe, carry case and software.

Testo 300 LL NOx Flue Gas Analyser

The Testo 300 LL NOx Flue Gas Analyser is designed for use on commercial boilers and combustion systems. In addition to oxygen, pressure, temperature, CO2, efficiency and more, it also stands out for its ability to measure CO up to 30,000ppm thanks to H2 compensation and automatic dilution.

Additionally, The Testo 300 LL NOx is fitted with a nitric oxide sensor that can offer readings of between 0 and 3000ppm thanks to a preset NO2 limit. Calculation features on the analyser itself can even provide readings for mg/kWh so the user can check whether an appliance meets the standards in the new European Directive (56mg/kWh for gas and LPG; 120mg/kWh for oil).

Aside from its high-grade measurement capabilities, the Testo 300 LL NOx also offers the user sleek, modern operation thanks to its vibrant 5.1” colour touchscreen and smartphone-style operating system. Thousands of readings can be saved to its internal memory and it boasts a range of analytical functions with reporting and calculation applications.
