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 bought these Varify water hardness test strips to check if my home water softener is working right. My friend recommended them to me. They are really easy to use. Just dip one in the water for a few seconds, wait 30 seconds, and compare the color to the chart. The colors are clear enough to read, and I got consistent results when I tested a few times which matches what I expected. Good value with 150 strips in the bottle. It has 50 in the main container and then 2x full refill pouches with 100 more.

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.
