Very accurate pH measuring strips. I am happy with the product, and recommend using them with full confidence.
At first the measurements did not come out right because the immersion took a few seconds. That short time in the directions for use should be replaced with one second, as it was once written on an older version also sold by Elemental. If you enter for one second it will show correctly. I am happy with the product.
The 4-color pH indicator strips offer precise pH measurement. Complete set with colorimetric scale makes pH monitoring easy and accurate.
The instructions for use vague and useless . I assumed the graded part goes into the concoction for the ph reading, then tried the non graded part. I did not see any color change. I could say that maybe just the green color has lightened extremely! a little. What does that mean? There is no such example in the picture on the product examples. And the other colors are changing, so I don't understand what color does the ph ul indicate in this case? I also gave up adjusting the ph ul of the cream which was obviously not ok because it stings.
Effective for checking the ph in creams. It is better than the yellow colored one. Thanks
It gave me a bit of a headache until I figured out how to use it :). But now I know, and I am very happy with the choice. I recommend.
I was confused when I first used the strips, as a consequence I used up quite a lot of the set, but I finally figured it out: I noticed that I can guide myself very much by the shade of the first color (the green one). Good luck!
I use it to check the pH of all cosmetic preparations. It is superior to single color.
