It's better not to know pH than getting such terribly inaccurate results.

I ordered these to check acidity and H levels in my gardens. I feel they are very accurate as they gave me different readings for three different charts and to double check I dipped a strip in pure lemon juice. The high acidity of the lemon juice is clearly visible on the strip. I am very happy with the packaging; displays different pH values to compare your strip. The instructions state that you must act quickly once you put the strip down, but I found I had plenty of time to compare my strip…
