JNW Direct 15-in-1 Drinking Water Test Kit - 100 Strips - Quick & Easy Water Testing Strip for Lead, Alkaline, Chlorine, Hardness, Iron, Fluoride, Copper & More

The only complain I have is that the colours have not the accuracy showing as the chart on the bottle. Some are hard to judge what colour it is with the numbers associated. But in general, it appears to be a good water testing kit.

I had a Kinetico water system installed a few months ago - ridiculously expensive - and I wasn't sure it was working, so I bought this kit to check it. I checked the kitchen hot and cold (let both run for quite some time), the bathroom, the outside tap, and some bottled water I use for drinking. Water softeners are supposed to condition all the water in the house except the kitchen cold tap and the outside tap. As you can see by the photo, the results are the same across the board except for the bottled water I used as a sort of control (I refill my bottles from Watermill Express). Las Vegas has hard water - it runs usually around 16.5 grains. The problem with the test strips is that hardness is measured at 0, 25, 50, 120, 250, 425 ppm. After a bit of research, I found that you have to take ppm and divide it by 17.1 to figure out what the grains come to. It looks like mine is running between 120-250, which correlates to 7-15 grains, but it doesn't tell me really where it is. It does tell me that, if the strips are accurate, my system isn't doing a damned thing to the water, so there's some value in that. The strips are really easy to use. Just dip them in the water for 2 seconds, then lay them flat for 10-30 seconds to let them fully develop. The packaging is excellent - no more than you really need, and the jar they come in is easy open/easy close. Even someone with arthritis should be able to handle it. I just made a small hole in the foil cover and shook out what I needed. The chart is pretty clear, though I'm definitely keeping the jar in the dark so the colors don't fade out. They also include a little e-book that gives more detail about each of the tests and what it means. For basic information, this test kit is okay. For detailed hardness testing, not so much. But it's worth what I paid, and it's easy to use.

As described. :) thanks for the product

Used it for testing home well water. The last time we had our water tested was when we bought the house in 1985. It was easy to use. One thing that I just thought of. There should be mention in the instructions that the test strip colors might be most accurately viewed in natural light. Several types of artificial light are not ideal for viewing colors. After natural sunlight, incandescent light is the best.
