The Accuracy Test Kit is the most accurate way outside of a laboratory to test your water quality and will measure down to 0PPM hardness.
You start by taking a measured dose of water using the smaller clear tube and pour this into the larger glass container. Then add a measured dose of pink testing reagent using the small black scoop. If the water turns blue, then you have completely soft water. If the water turns pink, then using the black dropper, add drops of the testing solution. How many drops you add are then multiplied by 17.1 to give you the PPM reading.
If your softened water is hard, contact us for a FREE Health Check on your softener.
