UHV-24/UHV-24p Ionization Gauge 

DRAFT 1/6/14

Warranty

Products manufactured by Seller are warranted against defects in materials and workmanship for twelve 
(12) months from date of shipment thereof to Customer, and Seller’s liability under valid warranty 
claims is limited, at the option of Seller, to repair, replace, or refund an equitable portion of the 
purchase price of the Product. Items expendable in normal use are not covered by this warranty. All 
warranty replacement or repair of parts shall be limited to equipment malfunctions which, in the sole 
opinion of Seller, are due or traceable to defects in original materials or workmanship. All obligations of 
Seller under this warranty shall cease in the event of abuse, accident, alteration, misuse, or neglect of 
the equipment. In-warranty repaired or replaced parts are warranted only for the remaining unexpired 
portion of the original warranty period applicable to the repaired or replaced parts. After expiration of 
the applicable warranty period, Customer shall be charged at the then current prices for parts, labor, 
and transportation.
Reasonable care must be used to avoid hazards. Seller expressly disclaims responsibility for loss or 
damage caused by use of its Products other than in accordance with proper operating procedures.
Except as stated herein, Seller makes no warranty, express or implied (either in fact or by operation of 
law), statutory or otherwise; and, except as stated herein, Seller shall have no liability under any 
warranty, express or implied (either in fact or by operation of law), statutory or otherwise. Statements 
made by any person, including representatives of Seller, which are inconsistent or in conflict with the 
terms of this warranty shall not be binding upon Seller unless reduced to writing and approved by an 
officer of Seller.

Warranty Replacement and Adjustment

All claims under warranty must be made promptly after occurrence of circumstances giving rise thereto, 
and must be received within the applicable warranty period by Seller or its authorized representative. 
Such claims should include the Product serial number, the date of shipment, and a full description of 
the circumstances giving rise to the claim. Before any Products are returned for repair and/or 
adjustment, written authorization from Seller or its authorized representative for the return and 
instructions as to how and where these Products should be returned must be obtained. Any Product 
returned to Seller for examination shall be prepaid via the means of transportation indicated as 
acceptable by Seller. Seller reserves the right to reject any warranty claim not promptly reported and 
any warranty claim on any item that has been altered or has been returned by non-acceptable means of 
transportation. When any Product is returned for examination and inspection, or for any other reason, 
Customer shall be responsible for all damage resulting from improper packing or handling, and for loss 
in transit, notwithstanding any defect or non-conformity in the Product. In all cases, Seller has the sole 
responsibility for determining the cause and nature of failure, and Seller’s determination with regard 
thereto shall be final.
If it is found that Seller’s Product has been returned without cause and is still serviceable, Customer will 
be notified and the Product returned at Customer’s expense; in addition, a charge for testing and 
examination may be made on Products so returned.
