WARRANTIES 

Goods furnished by the Seller are to be within the limits and of the sizes published by the Seller and subject to the Seller’s standard 

tolerances for variations. All items made by the Seller are inspected before shipment, and should any of said items prove defective due 

to faults in manufacture or performance under Seller approved applications, or fail to meet the written specifications accepted by the 

Seller, they will be replaced or repaired by Seller at no charge to Buyer provided return or notice of rejection of such material is made 

within a reasonable period but in no event longer than three (3) years for non-calibration defects and one (1) year for calibration 

defects from date of shipment to Buyer, and provided further, that an examination by Seller discloses to Seller’s reasonable 

satisfaction that the defect is covered by this warranty and that the Buyer has not returned the equipment in a damaged condition due 

to Buyer’s or Buyer’s employees’, agents’, or representatives’ negligence and Buyer has not tampered, modified, redesigned, 

misapplied, abused, or misused the goods as to cause the goods to fail. In addition, this warranty shall not cover damage caused by 

Buyer’s exposure of the goods to corrosive or abrasive environments. Moreover, Seller shall in no event be responsible for (1) the cost 

or repair of any work done by Buyer on material furnished hereunder (unless specifically authorized in writing in each instance by 

Seller), (2) the cost or repair of any modifications added by a Distributor or a third party, (3) any consequential or incidental damages, 

losses, or expenses in connection with or by reason of the use of or inability to use goods purchased for any purpose, and Seller’s 

liability shall be specifically limited to free replacement, or refund of the purchase price, at Seller’s option, provided return or rejection 

of the goods is made consistent with this paragraph, and the Seller shall in no event be liable for transportation, installation, 

adjustment, loss of good will or profits, or other expenses which may arise in connection with such returned goods, or (4) the design of 

products or their suitability for the purpose for which they are intended or used. Should the Buyer receive defective goods as defined 

by this paragraph, the Buyer shall notify the Seller immediately, stating full particulars in support of his claim, and should the Seller 

agree to a return of the goods, the Buyer shall follow Seller’s packaging and transportation directions explicitly. In no case are the 

goods to be returned without first obtaining a return authorization from the Seller. Any repair or replacement shall be at Seller’s factory, 

unless otherwise directed, and shall be returned to Seller transportation prepaid by Buyer. If the returned goods shall prove defective 

under this clause they will be replaced or repaired by Seller at no charge to Buyer provided the return or rejection of such material is 

made within a reasonable period, but in no event longer than (1) year from the date of shipment of the returned goods or the unexpired 

terms of the original warranty period whichever is later. If the goods prove to be defective under this paragraph, the Buyer shall 

remove the goods immediately from the process and prepare the goods for shipment to Seller. Continued use or operation of defective 

goods is not warranted by Seller and damage occurring due to continued use or operation shall be for Buyer’s account. Any 

description of the goods contained in this offer is for the sole purpose of identifying them, and any such description is not part of the 

basis of the bargain, and does not constitute a warranty that the goods will conform to that description. The use of any sample or 

model in connection with this offer is for illustrative purposes only, is not part of the basis of the bargain, and is not to be construed as 

a warranty that the goods will conform to the sample or model. No affirmation of that fact or promise made by the Seller, whether or 

not in this offer, will constitute a warranty that the goods will conform to the affirmation or promise. THIS WARRANTY IS EXPRESSLY 

IN LIEU  OF ANY AND ALL OTHER EXPRESS OR IMPLIED WARRANTIES WITH RESPECT TO THE GOODS OR THEIR 

INSTALLATION, USE, OPERATION, REPLACEMENT OR REPAIR, INCLUDING ANY IMPLIED WARRANTY OF 

MERCHANTABILITY OR FITNESS OF PURPOSE; AND THE GOODS ARE BEING PURCHASED BY BUYER “AS IS”. SELLER WILL
