Water Hardness Test Kit

Want to know the hardness of your water before buying the correct water softener? Or maybe test the efficiency of your current softener. This easy to use test kit is the ideal way to do it.


Place 10ml water sample in the vial provided.
Add 1 drop of the hardness reagent, if the sample immediately turns blue you already have soft water.
If the sample turns red continue adding drops of the hardness reagent one at a time, mixing after each drop is added.
Keep a count of the drops added until the solution turns from red to blue.
Each drop represents 20 ppm (Parts per Million) hardness, so you can easily calculate your total hardness in seconds.
Instructions are included.

Each kit is good for approx 250 drops so can be used again & again, great for regular testing.
