Greetings Chilidog:
Here's a site I've found helpful and informative.
http://www.leeners.com/condiments-hotsauce.html
They also sell pH test strips (range= 2.2 to 4.4 sold with their wine making supplies))which I use to determine if the pH level of my sauce is acceptable for "water bath" processing or if I must use a pressure canner.
Their test strips are $6.95 /100 and for the peace of mind using them brings me...they are well worth the cost.
