Technical Specifications

What's in the Box

• Testo Modular Flue Gas Probe (0600 8764) with 335mm shaft
• Integrated NiCr-Ni Thermocouple (Tmax 1000 °C)
• NO₂/SO₂ Special Hose (2.2 m length)
• Cone for attachment

Using It on the Job

1. Confirm your Testo 340 or 350 analyser is calibrated and ready for use.
2. Securely attach the probe's bayonet fitting to the analyser, ensuring a tight seal for both gas and temperature channels.
3. Insert the 335mm probe shaft into the flue, using the provided cone for proper positioning and sealing to prevent ambient air ingress.
4. Allow the temperature reading to stabilise before taking your measurements to ensure accuracy.
5. After use, carefully remove the probe and inspect the shaft and hose for any signs of wear or blockage.
6. Clean the probe and replace any particle or sintered filters as needed to maintain accuracy for your next job.

Limitations & Safety Notes

• Only for use with compatible Testo 340 and Testo 350 series combustion analysers.
• Ensure the probe shaft is fully cooled before attempting to swap it out to prevent burns.
• Always wear appropriate PPE, including eye protection and heat-resistant gloves, when working near hot flues or combustion gases.
• Regularly check the hose and probe for damage; replace worn components to prevent leaks and ensure accurate readings.
• Follow Australian standards and Safe Work guidance for all combustion analysis procedures.

Tradie Pro Tip

Keep an eye on your particle filters. A clogged filter will throw off your readings and make your pump work harder. Swapping them regularly means you're always getting reliable data and extending the life of your analyser.
