Testo 300 Basic Flue Gas Analyser Kit

This Testo 300 Basic Flue Gas Analyser Kit (SKU 530564 3170) is built for HVAC and plumbing pros who need to check combustion efficiency and emissions on heating systems. It comes with everything you need to get straight to work, ensuring your installations and services meet the mark.

In Australia, getting accurate flue gas readings is critical for safety, efficiency, and compliance, especially with the range of heating systems out there. I've been in situations where a quick, reliable check prevented a callback, so having a responsive, accurate tool like this is a real time-saver on the job.

Best For

• HVAC technicians performing routine heating system maintenance.
• Plumbers installing or commissioning new gas heating appliances.
• Service teams diagnosing combustion issues.
• Apprentices learning flue gas analysis fundamentals.

Compatibility

This kit is designed for comprehensive flue gas measurement on a wide range of heating systems. It’s equipped to handle standard residential and light commercial heating setups, providing readings for O₂ and CO up to 4,000 ppm. The compact basic flue gas probe is rated for temperatures up to 500 °C, suitable for most common applications. If you're running a different model or working with specialised industrial systems, check specific temperature and pressure requirements before ordering.

Features

• Smart-Touch Display: Features a fast-response 5.0" HD touch display, making navigation and data input as easy as using your smartphone.
• Integrated O₂ and CO Sensors: Comes with pre-installed sensors for oxygen (0 to 21 Vol.%) and carbon monoxide (0 to 4000 ppm), ready for immediate use.
• Basic Flue Gas Probe Included: The 300 mm, Ø 6 mm compact probe handles flue gas, draught, and temperature measurements up to 500 °C.
• Wireless Connectivity: Allows for parallel measurement with up to four Testo Smart Probes (sold separately), great for complex diagnostics.
• Data Management: Includes EasyHeat software for simple data integration and report generation, helping you create professional documentation on site.
• Robust Design: IP40 protection class means it’s built tough enough for daily job site conditions, from dusty plant rooms to exposed rooftops.

Technical Specifications

What's in the Box

• Testo 300 NEXT LEVEL flue gas analyser (O₂ and CO sensor up to 4,000 ppm)
• Compact basic flue gas probe (300 mm, Ø 6 mm)
• USB mains unit with 2 m cable
• Spare dirt filters (10 off)

Using It on the Job

1. Power On & Warm Up: Ensure the analyser is fully charged or connected to the mains. Allow it to warm up as per manufacturer instructions for accurate sensor calibration.
2. Connect Probe: Securely attach the basic flue gas probe to the analyser. Check all connections for a tight fit to prevent ambient air ingress.
3. Insert Probe: Carefully insert the flue gas probe into the sampling point of the heating system, ensuring the tip is positioned correctly in the flue stream as per Australian standards.
4. Take Readings: Use the Smart-Touch display to navigate to the relevant measurement menu (e.g., O₂, CO, draught). Allow readings to stabilise before recording or saving.
5. Document & Report: Utilise the EasyHeat software to transfer data and generate reports on site. Email reports directly from the device to customers or your office.
6. Post-Use Care: After each job, ensure the probe is cleaned, and the analyser is stored safely in its case, especially if working in dusty conditions.

Limitations & Safety Notes

• This analyser is for flue gas and related heating system measurements; it is not for general refrigerant leak detection.
• Ensure the probe temperature limit of 500 °C is not exceeded to prevent damage to the probe and sensors.
• Always follow manufacturer guidelines for calibration and sensor replacement to maintain accuracy and compliance.
• Follow all relevant Australian gas regulations and Safe Work Australia guidance when working on heating systems.
• Periodic maintenance of the dirt filters is essential to protect the sensors and ensure accurate readings.

Always let your analyser warm up fully and zero out in fresh air. It sounds basic, but rushing that step means your initial readings could be off, costing you time and accuracy later on. It's a non-negotiable for reliable combustion analysis.
