I have a few extra packs of 7 and 10 calibration fluid if needed...

Alex,

There's a scientific supply place near your house whgere you can get it. Let me see if I can find it for you. Its on Bandera.

Edit: http://www.analyticalsci.com/

I think I'm going to stop in there and pick up some pH 6.5-10 test strips to use as a quick test. A lot easier and cheaper than a pH meter. No need for calibration. I have some 0-14 strips but they are not specific enough.
