My order was delivered the very next day, securely packed. The product is presented in a little white and dark green card box.
The base of the holder is made of a black hard plastic and the top is made of clear hard plastic. The case is 5 cm (diameter) x 1.5 cm. The little roll is 5 meters long and comes extra protected into a foil paper and it is very easy to set on its case, which remembers a stick tape system with a little dented cutter.
On the case, is a card attached with a scale guide – from 0 to 14 and the colors which may appear on your stripe.
It is very easy and simple to use - simply tear of a small portion of the strip for testing.
The strips can also be used for human urine, oral saliva sample and etc.
In general, a water with a pH _ 7 is considered acidic and with a pH _ 7 is considered basic. The normal range for pH in surface water systems is 6.5 to 8.5 and for groundwater systems 6 to 8.5. Alkalinity is a measure of the capacity of the water to resists a change in pH that would tend to make the water more acidic.
We have tested our water and we figured out that our water is right to drink :)
