Warranty and returns

Hanna products are manufactured in our ISO 9001:2008 facilities, meeting the highest quality standards in the industry. Hanna’s high standards also apply should a product be returned due to defects in material or workmanship.

To our private customers only

If you are not 100% satisfied with your purchase, you can return the product and get a full refund or exchange the product for another one, be it similar or not. You can return a product for up to 14 days from the date you purchased it. 

Any product you return must be in the same condition you received it, in the original packaging and the closing seal must be unbroken. Please keep the receipt.


Warranted products may be returned for repair or replacement only at the discretion of Hanna. In some circumstances, the remedy may constitute a refund for the price paid for the product.

To initiate the warranty for your Hanna meter, please fill out the registration form you can find on our Hanna web site: hannaservice.eu/warranty-activation. Only upon submitting your form, your product will be covered under the following Hanna warranty plan.

The purchased Hanna product is warranted for 18 months against defects in workmanship and materials when used for their intended purpose and maintained according to instructions. All Hanna electrodes and testers are warranted for six months. This warranty is limited to repair or replacement.

Damage due to accidents, misuse, tampering or lack of prescribed maintenance is not covered.

If service is required, contact the dealer from whom you purchased the instrument. If under warranty, report the model number, date of purchase, serial number and nature of the problem. If the repair is not covered by the warranty, you will be notified of the charges incurred.

If the instrument is to be returned to Hanna Instruments (for warranty and non-warranty service, replacement, recalibration, and repairs), first obtain a Return Goods Authorization (RGA) number from the Customer Service department (assistance@hannaservice.eu) and then send it with shipping costs prepaid. Any instrument not bearing an RGA number will be refused. All products returned for warranty repair or replacement MUST be preceded or accompanied with proof of purchase, such as the original invoice or packing list.

When shipping any instrument, make sure it is properly packed for complete protection. The sender is responsible for expediting any damage claims placed against the carrier.
