Modular Flue Gas Probe 700mm for Testo Analysers

This Testo modular flue gas probe is a solid piece of kit for anyone doing combustion analysis on commercial and industrial burners. With a 700 mm shaft, it gets you deep into flues to grab accurate readings for efficiency checks and compliance reports.

Swapping out a damaged probe shaft in the field can save you a stack of downtime, and this modular design makes that process quick and simple. No more wrestling with seized connections or buying a whole new assembly when only part of it's worn out.

Best For

• HVAC service technicians maintaining commercial boilers and furnaces.
• Industrial burner commissioning and tuning teams.
• Regulatory compliance testing for emissions.

Compatibility

This modular flue gas probe is designed for use with Testo 340 and Testo 350 combustion analysers. It includes a specific NO₂/SO₂ special hose, ensuring correct gas sampling for these applications.

• Testo 340 - Combustion Analyser (all variants, e.g., 0632 3340, 400563 3342, 400563 3343, 400563 340M)
• Testo 350 - Portable Emission Analyser (e.g., 0632 3510, 0632 3511)

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

Features

• Modular Design: Quick-change click system on the handle allows for easy and rapid replacement of the probe shaft in the field, reducing downtime.
• High-Temperature Thermocouple: Integrated NiCr-Ni (Type K) thermocouple reliably measures temperatures up to 500 °C.
• Secure Bayonet Lock: Flue gas path and temperature channel connect securely to your Testo instrument via a practical bayonet lock.
• Specialised Gas Hose: Includes a 2.2 m NO₂/SO₂ special hose, crucial for accurate readings in these applications.
• Optimal Dimensions: 700 mm probe shaft length and 8 mm diameter ensure suitable immersion depth and fit for a wide range of flue sizes.

Technical Specifications

What's in the Box

• Testo Modular Flue Gas Probe with 700 mm shaft (0600 9767)
• Integrated NiCr-Ni (Type K) thermocouple
• Cone for attachment
• NO₂/SO₂ special hose (2.2 m length)

Using It on the Job

1. Inspect Before Use: Always check the probe shaft, hose, and connections for any damage or blockages before hooking it up. A cracked shaft or pinched hose will give you garbage readings.
2. Connect to Analyser: Securely attach the probe to your Testo 340 or 350 using the bayonet lock. Ensure all connections are snug to prevent leaks or air ingress.
3. Insert into Flue: Position the probe in the flue to get an accurate, representative sample of the gas. The 700mm length is good for getting past turbulence at the opening.
4. Perform Measurement: Follow your analyser's specific instructions for purging, zeroing, and taking readings. Allow temperatures to stabilise.
5. Clean & Store: After each use, allow the probe to cool. Clean any soot or debris from the shaft and filters. Store properly to protect the thermocouple and hose.

Limitations & Safety Notes

• Maximum operating temperature for the integrated thermocouple is 500 °C. Exceeding this can damage the sensor.
• Only for use with compatible Testo 340 and Testo 350 combustion analysers.
• Ensure the probe is securely fitted and the system is leak-free to avoid inaccurate readings and potential hazards from flue gases.
• Regularly check and replace particle and sintered filters to maintain measurement accuracy and protect your analyser.
• Always follow manufacturer guidelines for your Testo analyser and local Safe Work Australia practices when conducting combustion analysis.

When you're dealing with high temps and corrosive gases, the little things count. Keep spare sintered filters handy – a clogged filter can skew your readings and put extra strain on your pump. It's cheap insurance.

Pair With

Pair this modular probe with a Testo 340 or Testo 350 Combustion Analyser for a complete setup. Don't forget to grab some spare Testo Sintered Filters and Particle Filters to keep your system running clean and accurate.
