Testo NO2 Retrofit Sensor for Flue Gas Analysers

This Testo NO₂ retrofit sensor lets you add nitrogen dioxide measurement to your compatible Testo flue gas analyser. It's a solid upgrade for any tech needing to track NO₂ levels in commercial or industrial exhaust, helping you meet environmental compliance or fine-tune combustion efficiency. Being precalibrated means less fuss on-site and more accurate readings from the get-go, especially when you're on a busy rooftop job and need reliable data fast.

Best For

• Expanding measurement capabilities of Testo flue gas analysers.
• Commercial and industrial combustion analysis.
• Environmental compliance checks for NO₂ emissions.
• HVAC/R technicians and industrial maintenance teams.

Compatibility

This NO₂ sensor is designed for direct integration with specific Testo flue gas analysers. It’s a perfect fit for:

• Testo 340 - Combustion Analyzer for Commercial and Industrial Applications (SKU: 0632 3340)
• Testo 350 - Portable emission analyzer (SKU: 0632 3510)

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

Features

• NO₂ Measurement: Enables accurate nitrogen dioxide readings in flue gas.
• Precalibrated: Ready to use straight out of the box, saving on field calibration time.
• Effortless Installation: Designed for easy self-insertion into compatible Testo analysers.
• Parameter Activation: Automatically activates the NO₂ measurement function in the analyser.

Technical Specifications

What's in the Box

• 1 x Testo NO₂ retrofit sensor (SKU: 0554 2200)

Using It on the Job

1. Ensure your Testo flue gas analyser (e.g., Testo 340 or 350) is powered off and disconnected from any probes or power sources.
2. Following your analyser's manual, carefully access the sensor bay for replacement.
3. Gently insert the precalibrated NO₂ sensor into its designated slot until it’s fully seated.
4. Close the sensor bay and power on your analyser. The instrument should automatically detect and activate the NO₂ measurement parameter.
5. Perform a zeroing or fresh air calibration sequence according to your analyser’s instructions before starting any flue gas measurements.
6. Once measurement is complete, power down the analyser and store it in its case to protect the sensors.

Limitations & Safety Notes

• This sensor is specifically for compatible Testo flue gas analysers (Testo 340, 350). It will not function as a standalone NO₂ measurement device.
• Always consult your analyser's operating manual for precise sensor replacement procedures and safety guidelines.
• Ensure the analyser is powered off before installing or removing any sensors to prevent damage or incorrect readings.
• Handle sensors carefully; while robust, they are precision instruments.

Tradie Pro Tip

Always keep spare, precalibrated sensors like this NO₂ module on hand. When you're out on a critical job and a sensor reaches end-of-life, being able to swap it quickly means less downtime and accurate measurements when they count most.

Pair With

This sensor is designed to work seamlessly with the Testo 340 and Testo 350 flue gas analysers. Consider pairing it with a range of Testo flue gas probes and filters to ensure your analyser is fully equipped for any industrial combustion task.
