Where can I get a pH indicator?

VEN asked:

I have to test the pH of about 200 substances, so will I have to buy 200 individual test strips? I also heard about indicator pens. Are those reusable? I would appreciate any help :) Thanks!!

    You can also try the pet store — ph indicators are used for saltwater fish tanks!

    Any decent pool store will have them, but they may not indicate the entire range you may need for two hundred items!

    Call your local university or college. they usually have stuff like this on hand. You might be able to rent a real pH meter that will do this all faster with higher accuracy
