Warranty Information
UNI-T Limited Warranty
3-Year Warranty on Instruments. 1-Year Warranty on Accessories.

1. Warranty Period
UNI-T provides the following standard warranty coverage:
| Product Category | Warranty Period |

2. Warranty Start Date
The warranty period begins on the original purchase date shown on a valid invoice or receipt issued by UNI-T or an authorized UNI-T distributor.

Customers are advised to retain their original invoice or receipt as proof of purchase.
Product Registration
Product registration does not change the original warranty start date.
Where a product is eligible for an applicable warranty extension through product registration, the additional warranty period is calculated from the original purchase date, not from the registration or approval date.
