Water Hardness Tester YD300 - Ukur Kesadahan Air
Product Code: YD3000

Definisi Water Hardness
Kesadahan air (hardness) adalah kandungan mineral-mineral tertentu di dalam air. Umumnya ion kalsium (Ca) dan magnesium (Mg) dalam bentuk garam karbonat.
Kesadahan merupakan petunjuk kemampuan air untuk membentuk busa apabila dicampur dengan sabun.
Pada air dengan kesadahan rendah, air akan dapat membentuk busa apabila dicampur dengan sabun.
Sedang pada air berkesadahan tinggi tidak akan terbentuk busa.
Air sadah atau air keras adalah air yang memiliki kadar mineral yang tinggi, sedangkan air lunak adalah air dengan kadar mineral yang rendah.
Selain ion kalsium dan magnesium, penyebab kesadahan juga bisa merupakan ion logam lain maupun garam-garam bikarbonat dan sulfat.
Metode paling sederhana untuk menentukan kesadahan air adalah dengan sabun. Dalam air lunak, sabun akan menghasilkan busa yang banyak. Pada air sadah, sabun tidak akan menghasilkan busa atau menghasilkan sedikit sekali busa. Cara yang lebih kompleks adalah melalui titrasi.
Kesadahan air total dinyatakan dalam satuan ppm berat per volume (w/v) dari CaCO3.
