Good way to test for low PH

I have a couple of shrimp tanks with active soils that test at 6.0 on the standard low range API PH test kit. I assume the PH may be lower than that and mainly out of curiosity would like to test it. Is there are reasonably priced test kit that goes down to at least 5.0? Alternatively does anyone have recommendation of a reliable PH pen that I could use between multiple tanks that would cover this range?
