Testo Modular Flue Gas Probe with NO2/SO2 Hose

This Testo modular flue gas probe is your go-to for precise combustion analysis, helping HVAC techs, plumbers, and industrial teams fine-tune systems and diagnose issues fast. It's built tough for Australian conditions, whether you're working on a rooftop boiler in summer or an industrial burner in winter.

Anyone who's swapped out a probe mid-job on a cold morning will appreciate the quick-change system; it saves time and hassle when you're under the pump.

Best For

• HVAC technicians
• Commercial plumbers
• Industrial maintenance teams
• Boiler service specialists
• Anyone performing combustion efficiency tests

Compatibility

This modular flue gas probe is engineered to connect seamlessly with Testo 340 and Testo 350 series combustion analysers. It ensures accurate and reliable data transfer for both flue gas composition and temperature readings.

If you're running a different model, check fittings and specs before ordering.

Features

• Quick-Change Click System: Easily replace the probe shaft on the fly, saving precious time during service calls.

• Integrated NiCr-Ni Thermocouple: Provides accurate temperature measurements up to 500 °C (932 °F).

• Bayonet Lock Connection: Securely links the flue gas path and temperature channel to your Testo analyser.

• Special NO2/SO2 Hose: Includes a 2.2 m hose specifically designed for robust sampling of these gas components.

• Robust Probe Shaft: Measures 335 mm in length and 8 mm in diameter, built for demanding environments.

Technical Specifications

What's in the Box

• Modular flue gas probe, 335 mm
• Cone for attachment
• Integrated thermocouple NiCr-Ni (TI)
• NO2/SO2 special hose, 2.2 m

Using It on the Job

1. Ensure your Testo 340 or 350 analyser is powered on and calibrated.
2. Connect the probe's bayonet lock to the appropriate port on your analyser, ensuring a tight seal.
3. Insert the probe into the flue gas duct or chimney, positioning it correctly for accurate sampling. Use the cone for secure attachment if needed.
4. Monitor flue gas temperature and composition readings on your analyser.
5. If a probe shaft needs replacement, use the quick-change click system for fast and simple swapping.
6. After use, remove the probe, disconnect the hose, and clean both thoroughly to prevent residue build-up.

Limitations & Safety Notes

• This probe is specifically designed for Testo 340 and 350 series combustion analysers.
• Do not expose the probe to temperatures exceeding its 500 °C (932 °F) maximum rating, as this can cause damage.
• Always ensure all connections are secure to prevent gas leaks, which can be hazardous and lead to inaccurate readings.
• Regularly inspect the probe shaft and hose for any signs of wear, cracks, or blockages, replacing components as needed.
• Follow manufacturer guidelines and local safety regulations when performing combustion analysis.

Tradie Pro Tip: Always keep your probe clean, especially the thermocouple tip. Soot build-up can slow down your temperature readings, making it harder to get that perfect tune on a boiler or burner.

Pair With

Pair this modular probe with your Testo 340 or Testo 350 combustion analyser and keep spare sintered or particle filters on hand for uninterrupted operation.
