Note: We have found that the products suggested above meet or exceed the specifications of the original NSN item.  This does not mean, though, that they may be substituted in place of the NSN item on a Government Contract.  We provided the above information as possible sources of water quality testing products for consideration in future Contracts/Bids only.
