If a clumbsy bee accidently dropped his much loved (and expensive) pH meter/electrode (doh!)....and was in need of a very quick and cheap replacement until he gets the real deal again would.....
Those urine test strips available at the pharmacy have a pH reading in the order of 5-9. This is a greater range than pool test strips, and comparably priced.
Has anybee used them...or should he use something else?
