Nutrafin tests rarely make it to their "good-until-one-year-after-manufactured-date" claim.

I know I've had to throw out a nutrafin kit. It hadn't worked accurately since the day I opened it. That was a different kit than pH however.

I'm not saying your kit is innacurate but it might be a good idea to test it against a substance with a known pH level just to be certain.

i know it says good until 2014 so its still relatively new...i didn't check the manufacture date but i should have. i like your idea about testing something with a known ph.....maybe i'll go test lemon juice. that seems like a fairly stable pH substance. CRAP i thought i was buying a good kit. you know i never even took into account that there was more then one kind of "master test kit" so every time i heard someone saying use a master kit or get a master kit it was the first one that came to mind. i'll test something with a known pH and if its right i'll be really happy but if not this would be a big waste of money
