Warranty and Service

Product Warranty Information

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.

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

The warranty period commences from the original date of sale to the user or a maximum of 18 months from the factory ship date. Warranty is valid only when the product is used under normal conditions and in accordance with operating limitations and prescribed maintenance procedures. The express warranty stated previously is the only express warranty given by Hanna Instruments to the end-user buyer. Hanna expressly disclaims any warranties implied by law, including but not limited to warranty of merchantability of fitness for a particular purpose. Hanna shall not be liable for any individual or consequential damages of any kind for breach of any warranty, or negligence, on the basis of strict liability or otherwise. Hanna’s warranty periods differ across our range of instrumentation. 


Below is a general time frame of warranties for various categories of products. For any clarification or questions about a particular product, please contact your local Hanna representative for specific warranty information. 

Warranty Durations

Instrument Service

Warranty and non-warranty service, replacement, calibration and repairs are performed by actory trained service technicians at one of Hanna’s Technical Service Centers worldwide. All items must have a Return Goods Authorization (RGA) number that can be obtained by contacting the Hanna Technical Service Department. The RGA number should be clearly marked on the outside of the box and the unit shipped prepaid and insured. Any product 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 slip. Under special circumstances, it may be deemed necessary by Hanna to issue a Return in Advance(RIA). In such cases, the defective materials must be returned to Hanna within 30 days. Materials not returned within 30 days become chargeable. Materials must be packed properly to avoid damage during transport, which would render the warranty null and void. The sender is responsible for expediting any damage claims placed against the carrier.

In most cases, a flat minimum service charge applies to non-warranty repairs or recalibration. Please contact your local Hanna Technical Service Department for current rates. Any materials returned for repair which are considered non-warranty may be serviced at hourly cost (excluding parts) following subsequent notification and approval of such.
