Le testeur de duret\u00e9 de l\u2019eau<\/a>\u00a0est un kit d\u2019analyse chimique con\u00e7u pour mesurer la duret\u00e9 totale de l\u2019eau<\/a>, exprim\u00e9e en degr\u00e9s allemands (\u00b0GH ou \u00b0DH), en d\u00e9terminant la concentration en ions calcium et magn\u00e9sium. Il est id\u00e9al pour les aquariums, les laboratoires, ou toute application n\u00e9cessitant un suivi pr\u00e9cis de la qualit\u00e9 de l\u2019eau.<\/p>\n

Le TH (Titre Hydrotim\u00e9trique) mesure la duret\u00e9 de l’eau en France, tandis que le GH (Gesamth\u00e4rte) est le terme allemand pour la m\u00eame mesure. Les deux indiquent la concentration en min\u00e9raux comme le calcium et le magn\u00e9sium, mais utilisent des \u00e9chelles de mesure l\u00e9g\u00e8rement diff\u00e9rentes. Pour les comparer, il faut utiliser un facteur de conversion (1 \\(GH\\) est environ \u00e9gal \u00e0 1,78 \\(TH\\)).<\/p>\n

Proc\u00e9dure de mesure :<\/strong><\/p>\n

    \n
  1. Rincer le flacon de test trois fois avec l\u2019\u00e9chantillon d\u2019eau \u00e0 analyser.<\/li>\n
  2. Pr\u00e9lever 5 ml d\u2019eau \u00e0 tester dans le flacon.<\/li>\n
  3. Ajouter 15 gouttes du r\u00e9actif n\u00b01, puis agiter l\u00e9g\u00e8rement.<\/li>\n
  4. Ajouter une dose (1 cuill\u00e8re) de poudre r\u00e9active, puis agiter jusqu\u2019\u00e0 dissolution homog\u00e8ne.<\/li>\n
  5. Ajouter goutte \u00e0 goutte le r\u00e9actif n\u00b02, en agitant entre chaque goutte jusqu\u2019\u00e0 ce que la couleur de l\u2019eau vire au bleu. Compter le nombre de gouttes n\u00e9cessaires.<\/li>\n
  6. R\u00e9sultat : Le nombre de gouttes du r\u00e9actif n\u00b02 utilis\u00e9 correspond directement \u00e0 la duret\u00e9 totale de l\u2019eau en \u00b0DH.<\/li>\n<\/ol>\n

    Conversion des r\u00e9sultats<\/strong> :<\/p>\n

      \n
    • 1 \u00b0DH = 17,857 mg\/L CaCO\u2083<\/li>\n
    • 1 \u00b0DH = 10 ppm (parties par million)<\/li>\n
    • 1 \u00b0DH = 0,178 mmol\/L CaCO\u2083<\/li>\n<\/ul>\n

      Ce test est simple \u00e0 utiliser, rapide et fiable. Il permet de contr\u00f4ler efficacement la qualit\u00e9 de l\u2019eau pour garantir un environnement stable, notamment en aquariophilie, en recherche ou en industrie.<\/p>\n","protected":false},"excerpt":{"rendered":"
