  • Aseko tester trdote vode

    Trdota vode je lastnost, ki izraža vsebnost raztopljenih mineralov (najpogosteje CaO in MgO) v vodi. Trdota vode je pomembna za njeno uporabo kot pitne in uporabne vode. Je vir nastajanja vodnega kamna in vpliva tudi na okusne lastnosti vode. Lahko je trajna in prehodna. Trajna vsebuje raztopljene kloride, sulfide, nitrate in silikate. Prehodna vsebuje raztopljen Ca (HCO3) 2 (kalcijev hidrogenkarbonat). Po njegovem izločanju nastane CaCO3 (kalcijev karbonat), kar je vodni kamen.

    Tester za določanje trdote vode. Test poteka tako, da testni papirnati trak pomočite v vodo in po eni minuti ocenite nastalo obarvanost glede na priloženo lestvico. Pakiranje vsebuje 10 meritev.

    Testne lističe zaščitite pred sončno svetlobo in vlago. Shranjujte na hladnem in suhem mestu pri temperaturi, ki ne presega 30 °C. Ne dotikajte se barvnih površin.
