 INSTRUMENT CO. ARE WARRANTED FOR A PERIOD 

OF ONE YEAR AGAINST DEFECTS IN MATERIALS AND WORKMANSHIP. THE TERMS OF THIS 

WARRANTY ARE AS FOLLOWS:

1.  The warranty period begins with the shipping date of the equipment to the original purchaser.
2.  Certain parts such as batteries, fused, glass accessories, septa, columns, etc., are expendable in normal use, 

and their service life is unpredictable. Such items are not covered by this warranty.

3.  Filaments of thermal conductivity detectors are not covered by this warranty.
4.  All requests for service or repair under this warranty must be received within the warranty period by

 or its authorized representative. All repairs are made at GOW-MAC plants or at the offi  ce of 

authorized representatives.

5.  All repairs, adjustments, and other service under this warranty shall be performed free of charge to the 

purchaser. However, warranty service and repairs shall be limited to equipment malfunctions which, in the 

opinion of GOW-MAC

®

, are due or traceable to defects in original materials or workmanship. Instrument 

malfunctions caused by abuse or neglect of the equipment are expressly not covered by this warranty.

to the purchaser at the then current prices for parts, labor, and transportation.

8.  This warranty attaches to the equipment itself and is not limited to the original purchaser. Unexpired portions 

of the warranty are thus transferable to subsequent owners.
