SPERRY INSTRUMENTS LIMITED LIFETIME WARRANTY

Subject to the exclusions and limitations detailed below, Sperry Instruments provides a limited lifetime warranty on products  

of its manufacture will be free from defects in materials and workmanship under normal use and service.

Limited

Limited means that Sperry Instruments warrants to the original purchasers of products from Sperry Instruments authorized distributors at the 

time of shipment such products shall be free of defects in material and workmanship while the tool is used under normal working conditions. 

Standard wear and tear, dulling over time, overloading, misuse, and acts of God are not covered under warranty. This warranty does not cover 

batteries, fuses, or test leads.

When a warranty claim arises, the purchaser must contact Sperry Instruments. If the defect comes under the terms of this  

limited warranty, Sperry Instruments will arrange, at its sole discretion, one of the following options: 

• Product will be replaced

The purchaser is solely responsible for determining the suitability of Sperry products for the purchaser’s use or resale, or for incorporating 

them into articles or using them in the purchaser’s applications. The distributor is authorized to extend the foregoing limited warranty to its 

original purchasers in connection with the sales of Sperry products, provided that such products shall not have been altered by the distributor. 

The distributor shall be fully responsible for any warranties the distributor makes to its purchasers which are broader or more extensive than 

Sperry’s limited warranty. 

Lifetime Warranty

Warranty Limitation: The forgoing warranties are exclusive and are in lieu of all other express and implied warranties whatsoever, including but 

not limited to implied warranties of merchantability and fitness for a particular purpose. The foregoing warranties do not cover ordinary wear 

and tear, abuse, misuse, overloading, alterations, products which have not been installed, operated or maintained in accordance with Sperry’s 

written instructions. Test leads, fuses, batteries and calibration are not covered under any implied warranty. “Lifetime” of products that are no 

longer offered by Sperry will be either repaired or replaced with an item of Sperry Instruments choice of similar value. Lifetime is defined as 5 

years after Sperry discontinued manufacturing the product, but the warranty period shall be at least ten years from date of purchase. Original 

proof of purchase is required to establish original ownership of product.

No warranty will be honored unless an invoice or other proof of purchase date is provided to Sperry Instruments. Hand written receipts or 

invoices will not be honored.
