Varify 150 Strips Water Hardness Test Kit - Water Testing Kit for Home, Drinking, Well, Spa, Swimming Pool, Softener, Dishwasher - Hard Water Test Strips for Calcium, Magnesium (0-425 pmm, 150 Strips)

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!

It is VERY hard to use unless you have perfect colour vision There are minute differences between the colours the tested strip turns, and the colours printed on the chart are far more saturated than the strip colours; this makes comparison even more difficult. Save yourself the money and go to your local water company's website; there you will find an extremely accurate value! In the internet age, his product is as pointless as horse whips became a century ago.

Very hard to distinguish the colours. It also comes up with a different (about 50 lower) hardness than a liquid test kit. (OK, the liquid might be wrong but it is the one supplied by the softener manufacturer, so I'm inclined to believe that. I guess I'll have to get another tester to try and get a 2 out of 3 result.)

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

I've been waiting for something as simple and easy as this ever since I've had a water softener, so 15+ years. It's really easy to use, doesn't need batteries and this batch will likely last longer than I will. Great value too.

Does what it says on the tin. No.issues and easy to use to yest hard and soft water

Don't differerentiate between moderate water hardness and extreme water hardness. Wrote to the supplier for clarification a d received no response

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

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.

These water hardness test strips are very easy to use and provide quick results in about 30 seconds, just as advertised. The color chart is clear and simple to read, making it easy to determine the hardness level of the water. I also appreciate that the package includes 150 test strips, which offers great value for the price. They are perfect for testing drinking water, aquariums, water softeners, and household water quality. Accurate, convenient, and dependable—I highly recommend them!
