Premium Water Hardness Test Kit | Fast, Accurate Testing Strips for Softener, Dishwasher, Well, Spa, Pool | 150 Strips at 0-425 PPM | Calcium and Magnesium Total Hardness

NNot functioning correctly. The strip color remains unchanged even after testing before and after going through the water conditioner. I do not recommend this product.

I never really thought about water hardness until I started noticing white residue on my faucets and my skin feeling dry after showers. So I decided to test our water at home—and this kit made it incredibly simple. The colors were clear and easy to read, so there was no confusion at all. Within seconds, I finally understood what was going on with our water.

Very imprecise. Colors change and fade, and even if you manage to do it right, you end up with a wide scale between two colors and you have to estimate with a LOT of error margin. Buy an electronic tool instead, don’t waste your money on this.

Affidabile e si nota molto chiaramente la durezza del acqua

Great value.

Simple to use and effective in my opinion. what else is there to say. It does the job I was wanting it for. Thank You.
