  • Astralpool Tester prostega klora in pH znamke Lovibond

    Tester za merjenje vrednosti prostega klora in pH. Testirana voda se obarva in primerja z barvnim odtenkom na testerju, kateremu je dodeljena številčna vrednost pH ali prostega klora. Reagentne tablete so namenjene izključno za kemično analizo in se ne smejo uporabljati za druge namene.

    K testerju je priloženo pakiranje 20 tablet za merjenje vrednosti pH in 20 tablet za merjenje prostega klora

    • Območje klora: 0,1 - 3,0 g / m3
    • Več kot 20 mg/l broma lahko barvni indikator DPD
      razbarva.
    • Območje pH: 6,8 - 8,2
    • Vrednosti pH, manjše od 6,8, vedno dajejo rumeno obarvanost
    • Vrednosti pH, večje od 8,2, vedno dajejo rdečo obarvanost
    • Vzorce vode z nizko karbonatno trdoto
      (zmožnost vezave kislin 4,3 < 0,7 mmol / l) lahko
      izkrivljajo vrednosti pH.

    Primerjajte barvo raztopine 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 6,8 - 8,2. pH, višji od 8,2, vodi do nastanka različnih mineralnih motnosti ter nastajanja vodnega kamna in drugih oborin. pH, nižji od 6,8, povzroča korozijo kovinskih površin. Vrednost pH vpliva na topnost in učinek uporabljenih dezinfekcijskih sredstev.
