BAN - have you tried your pH meter yet? do you know if the buffer can be reused to recalibrate or do you need to use new buffer each time?
bentalphanerd said:Anything under 4 pH will keep well. Use vinegar to reduce it, lemon/lime juice is good also (ascorbic acid).
For your pics - host them somewhere like http://www.imageshack.us/ then copy & paste the "Thumbnail for forums (1)" link straight into your post.
