Water Test Kit for Water Hardness – At home collection for analysis at lab



In simple terms, water hardness is the amount of dissolved calcium and magnesium in the water.

General guidelines for classification of waters are: 0 to 60 mg/L (milligrams per liter) as calcium carbonate is classified as soft; 61 to 120 mg/L as moderately hard; 121 to 180 mg/L as hard; and more than 180 mg/L as very hard.

If you want to know (or get a second opinion on) the hardness of your water, are exploring expensive filtration or water softener options that you aren’t sure that you need, or if you want to find out if hard water might be impacting your appliances, dishes, or other household activity, this kit will let you collect a sample of your water yourself and then ship it to the lab for analysis. This is the water test for hardness as CaCo3, which can then be converted into other units (grains per gallon) that you might need.
