Testo Flue Gas Probe for Industrial Engines

This Testo flue gas probe is built for the tough conditions of industrial engine and catalytic converter testing, giving Australian techs reliable readings up to 1,000 °C. It's the kind of gear you need when you're on a remote site and a quick, accurate combustion measurement is critical for engine efficiency and compliance.

Designed for use with compatible Testo analysers, this probe handles high temperatures and overpressure without missing a beat, saving you hassle on those demanding industrial jobs.

Best For

• Industrial engine mechanics
• Commercial HVAC technicians
• Combustion tuning specialists
• Emissions compliance teams

Compatibility

This probe is designed to work seamlessly with various Testo combustion analysers, including:

• Testo 340 - Combustion Analyzer for Commercial and Industrial Applications (0632 3340)
• Testo 340 - Boiler and Burner Combustion Analyzer Kit (400563 3342)
• Testo 340 - Engine Kit (400563 3343)
• Testo 340 - Mining Tuner Kit (400563 340M)
• Testo 350 - Portable emission analyzer (0632 3510)
• Testo 350 - Control Unit (0632 3511)

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

Features

• Robust Metal Construction: Prevents the handle from melting due to radiated heat from hot flue gas ducts.
• Integrated Particle Filter: An additional filter in the hose protects your analyser from contamination, extending its service life.
• High Temperature and Pressure Rating: Handles flue gas temperatures up to 1,000 °C and overpressure up to a maximum of 100 mbar at the probe tip.
• Replaceable Probe Shaft: The probe shaft is easily interchangeable, making maintenance straightforward and cost-effective.
• Optional Thermocouple Ready: Can be used with an optional thermocouple for parallel flue gas temperature measurement.

Technical Specifications

What's in the Box

• Stainless steel probe shaft (335 mm long)
• 2-chamber sampling hose including particle filter (4 m long)
• Probe handle

Using It on the Job

1. Connect the probe securely to your compatible Testo analyser, ensuring the particle filter is clean and correctly seated.
2. Insert the probe into the flue gas duct, making sure it's positioned for an accurate sample without obstruction.
3. If using an optional thermocouple (sold separately), connect it and position for parallel temperature readings.
4. Perform your measurements, monitoring temperatures and pressures within the probe's rated limits (max 1,000 °C, 100 mbar overpressure).
5. After use, allow the probe to cool completely. Clean the shaft and check the particle filter for excessive build-up, replacing if necessary.
6. Store the probe carefully, ideally in a transport bag, to protect it from damage and contamination.

Limitations & Safety Notes

• This probe is only compatible with specified Testo flue gas analysers. Always verify your analyser model before use.
• Maximum operating temperature is 1,000 °C. Exceeding this can cause permanent damage to the probe.
• Always handle hot probes with appropriate Personal Protective Equipment (PPE), including heat-resistant gloves, after removal from flue gas ducts.
• Ensure the particle filter is regularly inspected and replaced as needed to prevent analyser contamination and ensure accurate readings.
• Always follow your analyser's specific operating instructions and Safe Work Australia guidelines for combustion analysis procedures.

Tradie Pro Tip

Keep a few spare particle filters on the truck. A clogged filter can throw off your readings and put unnecessary strain on your analyser's pump, especially on those dusty industrial sites.

Pair With

Pair with a Testo 340 or Testo 350 combustion analyser and a transport bag for probes to keep your valuable gear safe and organised in transit and on the job.
