Our clients are given the new and exciting possibility of prolonging – free of charge – the guarantee period for their Nivel System measuring instruments by additional 12 months and thus enjoying 24-month guarantee cover for their equipment. In order to prolong the guarantee period, the instrument (with serial number and purchase document) should be registered within 3 months of its purchase date. The registration is made by the user (not the seller - shop). In the case of registration of a user without the company/NIP - fill in/enter the gaps: NONE.
