Testo CO Replacement Sensor without H2 Compensation

This Testo CO Replacement Sensor is a direct swap for your compatible Testo flue gas analyser, keeping your combustion checks accurate and your reports reliable. When you're out on a job, a faulty sensor can throw off your readings, making it impossible to correctly diagnose a system.

Having a spare on hand or replacing a tired sensor is just good practice, especially in the Aussie climate where analysers work hard in varying conditions.

Best For

• HVAC service technicians
• Combustion analysis specialists
• Anyone maintaining Testo 330-1 or 327-2 flue gas analysers

Compatibility

This CO replacement sensor is specifically designed for use with the Testo 330-1 and Testo 327-2 flue gas analysers. If you're running a different model, check fittings and specs before ordering.

Features

• Direct Replacement: Engineered as a genuine spare part for seamless integration into compatible Testo analysers.
• Accurate CO Measurement: Restores the analyser's ability to provide precise carbon monoxide readings for safe and efficient combustion tuning.
• Non-H2 Compensated: Ideal for specific applications where hydrogen interference is not a concern or where an uncompensated reading is preferred.
• Manufacturer Standard: Built to Testo's specifications for reliability and performance in demanding trade environments.

What's in the Box

• Testo 0390 0115 CO Replacement Sensor without H2 Compensation

Using It on the Job

1. Before replacement, always power down your Testo analyser and refer to the analyser's user manual for specific sensor replacement instructions.
2. Carefully remove the old CO sensor following the manufacturer's guide, noting its orientation.
3. Install the new 0390 0115 sensor, ensuring it's seated correctly and any electrical contacts are clean and firm.
4. Power up your analyser and initiate a fresh calibration sequence. This is critical for accurate readings after any sensor change.
5. Perform a test measurement to verify correct operation and sensor response.

Limitations & Safety Notes

• This sensor is specified as 'without H2 compensation'. Be aware of this if your application involves fuels that produce hydrogen, which could interfere with CO readings.
• Only use this sensor with the compatible Testo 330-1 and 327-2 flue gas analysers.
• Always follow your Testo analyser's user manual for safe operation, maintenance, and sensor replacement procedures.
• Regular calibration of your analyser is essential to ensure measurement accuracy and compliance.

Tradie Pro Tip: After fitting any new sensor, always perform a full fresh air purge and calibration. Don't skip this step; it's the only way to ensure your readings are spot-on for the next job.
