The Shelf Life is the period of time after manufacturing that Gastec assures the quality of the Detector Tubes provided the storage condition described on the box is maintained. In order to maintain the highest level of quality and integrity Gastec date-stamps our Detector Tubes at the point of Manufacture rather than at the point of Shipping which provides a more specific and accurate expiry date. This ensures that the readings of the results are as accurate as possible and provides our customers with complete confidence when utilizing our Gastec detector tubes.

The description of the Shelf Life in our catalogs and other media will be modified from Years to Months.
