Varify 150枚 水硬度テストキット - 水テストキット 自宅 飲酒 井戸 スパ スイミング プール 柔軟剤 食器洗い機用 - 硬水テストストリップ カルシウム、マグネシウム(0-425 pmm、150 枚)

Easy to use and accurate. Results were quick and easy to read. Great value!

Truth be told - I was cynical However, I'm pleasantly surprised. The strips work very well, and I can be 100% sure about this because I have my water softener connected to the hot water only. This is how I wanted it to be setup. I do not want my drinking water softened any more than it is, I actually have a separate filter for that anyway So, I did two tests, and as you can see from the photo. Green is the hot water tap result, and light brown is the cold water tap result. In a nutshell my hot water is soft, and my drinking water is mildly soft. Perfect! All-in-all a conclusive result and there are plenty of strips to last a very long time Would I recommend this product? 100% YES!

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

These water hardness test strips are quick, accurate, and very easy to use. The color chart is clear, and I got results in about 30 seconds. They work great for checking tap water, filtered water, and my water softener. With 150 strips included, it's an excellent value for the price. I highly recommend them for anyone who wants to monitor water hardness at home.
