Testo SO2 Retrofit Sensor

This SO2 retrofit sensor is designed to plug straight into your compatible Testo flue gas analyser, adding sulphur dioxide measurement to your toolkit. It's a quick way for maintenance teams and industrial techs to expand their analyser's capabilities without sending the unit back to the workshop.

When you're dealing with industrial burners or process control, monitoring SO2 is crucial for compliance and efficiency, especially with the varied fuel sources we see across Australian plants. I've been in situations where having this ready-to-go sensor on hand saved a good few hours of troubleshooting.

Best For

• Industrial flue gas analysis
• Commercial combustion system maintenance
• Environmental monitoring and compliance checks
• Technicians expanding their Testo analyser's functionality

Compatibility

This SO2 retrofit sensor is specifically designed for integration with the following Testo flue gas analyser models:

• Testo 340 - Combustion Analyzer for Commercial and Industrial Applications (Model 0632 3340)
• Testo 350 - Portable emission analyzer (Model 0632 3510)
• Testo 350 - Process Kit (Model 400563 3511)

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

Features

• SO2 Measurement: Adds sulphur dioxide detection capability to your compatible Testo analyser.
• Self-Installation: Designed for easy insertion by the user, no special tools or service centre visit required.
• Precalibrated: Comes ready to go, ensuring accurate readings straight out of the box once installed.
• Activates Parameter: Automatically enables the SO2 measurement function within your flue gas analyser's software.
• Durable Housing: Built with robust plastic housing to withstand typical industrial environments.

Technical Specifications

What's in the Box

• 1 x SO2 retrofit sensor

Using It on the Job

1. Power Down: Always ensure your Testo flue gas analyser is powered off and disconnected from any sampling lines before opening the sensor compartment.
2. Locate Slot: Refer to your analyser's manual to find the correct sensor slot for SO2.
3. Insert Sensor: Gently slide the precalibrated SO2 sensor into its designated slot. Ensure it clicks or seats firmly.
4. Close & Power Up: Securely close the analyser's compartment cover, then power on the unit.
5. Function Check: Verify the analyser recognises the new sensor and activates the SO2 measurement parameter. A quick zero-calibration might be needed depending on your analyser model.
6. Sample & Measure: Once ready, connect your sampling probe and begin your flue gas measurements as usual.

Limitations & Safety Notes

• Only compatible with the specified Testo 340 and Testo 350 analyser models.
• Always follow the safety instructions in your Testo analyser's user manual.
• Ensure the analyser is powered off before handling or installing sensors to prevent accidental damage or electrical issues.
• Proper handling of flue gas samples is essential; always use appropriate PPE.

Keep an eye on the calibration date of all your analyser sensors, even the new ones. While this SO2 sensor is precalibrated, regular checks ensure you're always getting reliable data for those critical industrial combustion reports.

Pair With

Pair this SO2 retrofit sensor with your Testo 340 or Testo 350 flue gas analyser, along with any necessary sample probes and particulate filters from our Flue Gas Analysis category. Consider a calibration gas kit for field checks.
