Отзыв о Лакмусовая бумага (индикаторная) для проверки качества воды 80 шт, тест-полоски для измерения кислотности почвы, pH-тестер 1-14, для анализа воды от Ewa Grska ᠌
I definitely do not advise buying, the product disappointed.
It was necessary to determine the hardness of the water in order to add salt to the dishwasher, and for some reason, when requested, gave out this product all the time, although it does not determine hardness at all and acidity is not converted into hardness in any way. My cant of course. In general, keep in mind when buying a product - it has nothing to do with measuring stiffness.
- Inexpensive. Lots of stripes.
- It is quite difficult to assess the acidity of a particular medium by the color of the strip, because it is undesirable to apply wet paper to the color scheme - it will get wet, the colors will be distorted and then you will not be able to use it. And even with the closest location of the strip to the scheme, it is very difficult to unequivocally determine which color your result belongs to more. In general, the water managed to determine only the approximate range of acidity from 5 to 9. Decide how much this result suits you. It does not suit me.
