  • Astralpool Tester ECO za merjenje prostega klora (broma) in pH

    Raztopina OTO in Phenol (kapljice) za merjenje vrednosti prostega klora in pH v testerju bazenske vode.

    Test vsebnosti klora

    1. Rumeno epruveto testerja napolnite z analizirano vodo iz bazena do oznake. Vzorec naj bo odvzet približno 40 cm pod gladino in ne v bližini vodne linije.
    2. V epruveto dodajte 4 kapljice raztopine OTO (O-tolidin). Epruveto zaprite s pokrovčkom in pretresite, da dobite homogeno raztopino.
    3. Barvo raztopine primerjajte z barvno lestvico na testerju. Ustrezni odtenek določa količino prostega klora v mg/liter. Največja vrednost je 1–1,5 mg/liter (v skladu z Uredbo št. 135/2004 Ur. l. 0,3–1 mg/liter, odvisno od temperature bazenske vode)

    Test pH

    1. Rdečo epruveto testerja napolnite z analizirano vodo iz bazena do oznake. Vzorec naj bo odvzet približno 40 cm pod gladino in ne v bližini vodne linije.
    2. V epruveto dodajte 4 kapljice raztopine PHENOL RED. Epruveto zaprite s pokrovčkom in pretresite, da dobite homogeno raztopino.
    3. Barvo raztopine primerjajte z barvno lestvico na testerju. Ustrezni odtenek določa vrednost pH. Vrednost pH vode izraža stopnjo kislosti ali bazičnosti kemične snovi. Idealna vrednost za bazene je 7,2–7,6. pH, višji od 7,6, vodi do nastajanja različnih mineralnih motnosti ter vodnega kamna in drugih oborin. pH, nižji od 7,2, povzroča korozijo kovinskih površin. Vrednost pH vpliva na topnost in delovanje uporabljenih dezinfekcijskih sredstev.
