Hardness h2o Test Kit

2 test kits in 1 package. General Hardness (GH) and Carbonate Hardness (KH)

General hardness is the measure of calcium (Ca++) and magnesium (Mg++) ion concentrations dissolved in water. These minerals are present in municipal, well and bottled spring water. The level of general hardness in tap and bottled water depends on the source of the water and the treatment processes it has undergone.

Hard water (>200 ppm) is high in calcium and magnesium, while soft water (50 to 100 ppm) is low in these minerals. Our GH (General Hardness) Test measures GH in German degrees (°dGH). To convert °dGH to parts per million (ppm), multiply °dGH x 17.9. Note: ppm and milligrams per liter (mg/L) are equivalent.

Carbonate hardness (also known as alkalinity) is the measure of carbonate (CO32-) and bicarbonate (HCO3-) ion concentrations dissolved in water. These minerals are present in municipal, well, and bottled spring water. The level of carbonate hardness in tap and bottled water depends on the source of the water and the treatment processes it has undergone. Carbonate hardness helps stabilize pH in the water.

Water with a low KH level (50 ppm or less) will tend to be acidic. Water with very low KH are subject to rapid pH shifts, if not monitored carefully. Water with a high KH level (>200 ppm) usually has a high pH. Our KH (Carbonate Hardness) Test measures KH in German degrees (°dKH). To convert °dKH to parts per million (ppm), multiply °dKH x 17.9. Note: ppm and milligrams per liter (mg/L) are equivalent.
