Make sure that you have the reagent and whether it is a concentrate or ready-to-use mixture. If you do not have a dedicated reagent, the measurement will not be possible [the result will be incorrect].
Most devices come with a reagent that is ready to use.
If you have a condensed reagent, it must be diluted in RO water in a ratio of 1 to 9. This means that the preparation of 1 liter of
ready-to-use measurement solution requires mixing 100 ml of condensed reagent with 900 ml of RO water.
RO water. Below you will find a table with values facilitating correct preparation of the reagent.
Remember to stir the reagent used to measure KH values at least once a week. Otherwise, its concentration may be unstable.
