How does the water hardness test kit work?
The water hardness test kit has a chemical in it and is either in the form of a drop or strip.
You fill your test bottle/container with the amount of water dictated by the test kit instructions, dip the strip at one end or add a drop of test drop, and wait a few minutes. The kit is designed such that it will change to a specific color.
If you use a test drop, the water in the bottle you’re testing will change the color.
If you are using a test strip, the test strip will change the color.
The test kit is provided with the standard printed color chart.
Compare the color with the standard printed color chart provided with the kit to know your water hardness level.
Some brands provide a small glass bottle with a line marked on it.
The line is to guide you on how much water level to fill so as to get the right numbers.
