Varify Water Hardness Test Kit - Water Test Kit for Home, Drinking, Wells, Spa, Pool, Softener, Dishwasher and More - Hard Water Test Strip for Calcium, Magnesium and More (0-425 pmm, 150 Strips)

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.

Works great and is easy to use. Seemed really accurate. Would recommend.

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.

These are perfect especially for me as had an issue with our watersoftner, purchased these at a ridiculous price we'll worth the money.

Affidabile e si nota molto chiaramente la durezza del acqua
