Product registration

Thank you for choosing a flue gas analyzer from Testo.

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.

When you register your product, we will extend the regular manufacturer's warranty (either 2 or 4 years depending on the model) by one year (regardless of the model). We will also provide you with application-specific information about products, innovations, events and promotions relating to relevant products for flue gas measurement and keep you up to date with general developments in the flue gas market.

Testo product registration is subject to country-specific conditions.

Please click on “Next” to confirm that you would like to register the product in the country of your choice. If necessary, you will be forwarded to another country version of the Testo website.


Alternatively, you have the option of purchasing the one-year warranty extension for your measuring instrument for a fee (order number: 0991 3001; EUR 119.00 plus VAT), i.e. without further use of your e-mail address by Testo.

In this event, please contact our Testo Sales department:
