Testo CO2 Retrofit Sensor (IR)

This Testo CO2 retrofit sensor (IR), SKU 0554 2400, is a critical component for technicians performing flue gas analysis on heating systems and industrial processes. It allows you to easily add or replace CO2 measurement capability in compatible Testo emission analysers without needing a specialist service call.

For any tradie looking to keep their Testo 350 analyser running efficiently, being able to swap in a precalibrated sensor on-site means less downtime and accurate results when you're tuning a burner or checking combustion efficiency in the middle of winter.

Best For

• HVAC Technicians performing combustion analysis
• Plumbers and gasfitters working on heating systems
• Industrial maintenance teams monitoring emissions
• Compliance testing for boiler and furnace efficiency

Compatibility

This IR CO2 retrofit sensor is designed for simple, user-friendly integration with the following Testo emission analysers and kits:

• Testo 350 Portable Emission Analyser (SKU 0632 3510)
• Testo 350 Process Kit (SKU 400563 3511)

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

Features

• Easy Retrofit: Designed for quick, effortless insertion into compatible Testo 350 analysers by the user.
• Precalibrated: Arrives ready for immediate use, minimising setup time and ensuring accuracy out of the box.
• NDIR Technology: Utilises Non-Dispersive Infrared technology for reliable and precise CO2 measurement in flue gas.
• Robust Housing: Constructed from durable plastic, built to withstand typical worksite conditions.

Technical Specifications

What's in the Box

• 1 x CO2 retrofit sensor (IR)

Using It on the Job

1. Power Down Analyser: Always ensure your Testo 350 analyser is powered off and safely disconnected before opening any access panels or removing existing sensors.
2. Remove Old Sensor: Carefully unclip or disconnect the existing CO2 sensor, if present, following your analyser's instruction manual.
3. Insert New Sensor: Align the precalibrated 0554 2400 sensor into its designated slot. It should slide in effortlessly and click securely into place.
4. Power On & Check: Reassemble your analyser, power it up, and perform a brief self-test to confirm the new sensor is recognised and reporting correctly.
5. Perform Flue Gas Analysis: Once installed, you can proceed with your combustion and emission measurements, relying on accurate CO2 readings.
6. Post-Use Care: After use, ensure your analyser and sensors are stored in a clean, dry environment to protect them from contaminants.

Limitations & Safety Notes

• This sensor is designed exclusively for the Testo 350 series of emission analysers as specified.
• Intended for flue gas CO2 measurement only; not suitable for ambient air quality monitoring.
• Always refer to your Testo 350 analyser's user manual for specific installation and operating procedures.
• Regular maintenance and calibration of your analyser are crucial for sustained measurement accuracy.
• Follow all relevant Australian standards and Safe Work guidance when performing combustion analysis.

Tradie Pro Tip: Keep a spare sensor on hand if you're out on big commercial jobs. Nothing worse than having a CO2 sensor fail halfway through a multi-burner commission and having to down tools. Swapping this one out is a 5-minute job.
