Update on Test Strips in foil wrap.
I received a foil wrapped CC2602B test strip with a November 2011 expiry date. When I opened that strip it was VERY dead. I previously stated that the note that came out from our product line engineer on this product was that any strip with a date code of August 2011 or later was good.
This information is incorrect. He got it wrong. Sorry, but if you bought test strips based on my earlier note and found them to have the nitrite pad (top most) turning some shade of brown then they are also DOA. Return them to your supplier if you are able.
You may also contact me directly. I will see what I can do to help. Your first effort has to be with the supplier you bought them from. They will need to go to Fleetguard to get replacement product.
If the new strips you bought have a new plastic packaging that is different from the old packaging, you have the new product package that is expected to be good. I am sorry I cannot be more specific as I do not have any of the new product as yet so I have no picture. Neither do I have a real date code that is good.
If yours look like the attached, return them.
