  • Tester DPD „FR“ - Cl / pH - metoda s tabletami, pakiranje: etui

    Tester je namenjen testiranju prostega (aktivnega) klora in vrednosti pH bazenske vode. Da bo vaša bazenska voda kristalno čista, je uporaba testerja nujna. Vzemite vzorec vode iz vašega bazena in če izmerjene vrednosti ne bodo v mejah normale (pH 6,9-7,4 ; Cl 0,3-0,7 mg/l), jih popravite s pomočjo bazenske kemije. Najprej uravnajte vrednost pH (pH+ ali pH-), nato pa uravnavajte vrednost klora (le jo povečujte - če je vrednost klora previsoka, je ne znižujte, saj bo v nekaj dneh sama padla). Klor se dodaja šele po uravnavanju pH, ker učinkovitost klora zunaj priporočene vrednosti pH močno pade.


    Tester DPD deluje na principu vizualne primerjave z barvno lestvico ob merilnih komorah. Po dodajanju tablete Cl/pH v komoro se voda obarva, glede na rezultat pa je treba prilagoditi vrednosti Cl/pH v bazenu.

    Postopek:

    1. Razpakirajte tester
    2. Komori napolnite do oznake z vodo za testiranje (iz bazena).
    3. Test klora - v komoro Cl dodajte 1 tableto DPD 1. Tablete se ne dotikajte s prsti.
    4. Test pH - v komoro pH dodajte 1 tableto Phenol Red. Tablete se ne dotikajte s prsti.
    5. Zaprite testni komori in rahlo pretresite, da se tableti raztopita.
    6. Nato primerjajte obarvanost testirane vode s skalo vrednosti Cl in pH.
