Scan the QR code on the central heating sample bottle and complete all mandatory fields in the Fernox Water Test App. If the bottle is not scanned, it will not be registered and will fail to return a result. Place both bottles in the UPS return envelope, sign the customs declaration on the reverse of the envelope, and either drop the samples at a UPS location or arrange for UPS collection from your location.

Please note that postal delivery times will vary by country. Interpretation is based on the sample being treated with Fernox products and representative of the system as a whole.
