Johnson Test Papers Universal Indicator Paper, pH 1-11, Pack of 10 Book, 20 Strips Per Book by Johnson Test Papers

These are a good general strip for testing pH values of urine, saline or other liquids etc. They're very reasonable, there are 200 in a box and you can use just half a strip, so you could get 400 uses if necessary. They are divided into 10 little booklets with 20 strips in each and the colour chart is inside the covers of the booklet. The numbers however are only in full numbers, eg 5-6-7 and not subdivisions like 6-6.25-6.5 etc which I prefer as they're more accurate. I also found, that since the booklet is just held together with a kind of staple, it starts to come part half way through. This isnt a real problem as you can keep them in a small bottle or dish, and as long as they don't come in contact with bodily fluids or other substances that alter them, then they'd be fine. You wait about 15-30 seconds to get the full and final result, as you would with all such kits. Good value if you're not concerned about being really exact.

I use these for my soap making hobby to determine the pH. They are very good indicators and there are lots of them in a book. Good product.

I originally looked at the cheaper makes but bought these based on previous reviews. I'm still trying them on different foods and liquids but so far I'm pleased with my purchase. They arrived swiftly and in perfect condition.

Works like a treatHighly recommendedMake sure though to close the container properly otherwise the air will effect the strips hence effecting the result.

Very easy to use and instant reading on the papers. Can easily be slipped in a purse with no one needing to know. I bought these as I am following the alkaline plan.
