Product registration form for free warranty extension

Please take 2 minutes of your time to register your new product with us.

Product registration is a prerequisite for being granted a free one-year warranty extension. Furthermore, it is subject to your consent to receive application-specific information. Therefore product registration is only possible if you give us this permission. You can find our full product registration terms and conditions in our Privacy Policy. Here, you will also find the full terms and conditions of consent to receive application-specific information.


Alternatively, you have the option of purchasing the one-year warranty extension for your flue gas analyzer for a fee without further use of your e-mail address by Testo.

In this event, please contact our Testo Sales department:
