I can confirm that the measurement can be carried out very easily and this set probably
a perceived "eternity" anhaltet.
BUT: Accurate measurement is not possible. Man sees whether the values are below / above the ideal value, but
an accurate indication of value can hereby certainly not be durchegführt.
For my house used it fits, because I have little problem with the pool water anyway and I just wanted to know
in which "direction" the numbers.
Would I buy this set: No.
