Hardness and Iron Test Kit - Model HA-95A Hardness: - Water hardness is caused almost entirely by calcium and magnesium ion. Other di- and trivalent metals have a similar effect, but usually are not present in high enough concentration in potable waters to cause problems. Hardness increases soap consumption in laundries and causes scale in boilers.
Iron: - In domestic water supplies, iron can do great economic damage by staining laundry and porcelain fixtures and by producing an off taste in beverages. In water supplies used for commercial beverage production, low levels of iron are critical.
- Hardness and Iron Test Kit Model HA-95A is compact and convenient for routine checks.
