SJ WAVE 16 in 1 Drinking Water Testing Kits - 100 Strips (10 Strips Per Pouch) Water Testing Kits for Drinking Water, Home Tap and Well Water Test Kit for pH Hardness Lead Iron Copper Chlorine

These lead test swabs are super easy to use and give quick, clear results. They’re perfect for testing old paint, toys, or household surfaces. It’s a great product to have at home, especially with kids around. Definitely recommend for anyone looking for a simple way to check for lead!

It worked very quickly and was clear to understand and use!

Easy to use, lots of test strips. Was interested to test for lead given some local work done by the municipality in that regard, but the test is really too coarse for that, skipping from 0 mg per liter to 20 mg per liter on the readout, but where the recommended threshold for safety is < 3 mg per liter. So really kind of useless for that, apart from giving you a heads up that you may have extraordinarily high/dangerous lead. Bottom line, a decent test kit for massive bad news about lead, but not a test that can rule out that you have unsafe levels.

Easy to perform.Comorehensive

Did multiple water quality tests before installing my sink purifier and they seemed to work well. This is a good value for the money.

I personally don't love it. The normal parameters are not clear to me. I tested different waters and the colors are the same so I doubt if that really works.It is very easy to do it though

The instructions and procedures were easy to follow. Takes very little time to complete. The color chart is the exact size needed to align the test strip to ensure you read the correct line no guessing needed. Not only is there a chart on the box, but also one included on the instruction page as well. I will be buying these test strips again when needed. In the pictures, a test of my tap water and a test of distilled water for comparison.Update. After more than a month of using these strips, I have become more and more impressed with them. They have been instrumental in assuring the tap water I de-chlorinate (I mix 25mg vitamin C per gallon of water to de-chlorinate it) is sufficient for my use. They are sized just right to fit right beside the color chart for easy reading. I really like the resealable bags that hold 10 strips each so all strips are not exposed to the air when I get one out to use. Each bag also has a deaccent packet to keep the moisture in the packet controlled. I’ll definitely be buying these again!!

I just received this kit two days ago. I noticed that the expiration date is 14Mar26, which was not noted in the product details of the Amazon iOS app. I was curious about it so I checked the manufacturer’s website, and it states that consumers should expect a two-year shelf life for these kits, and only 90 days for the individual strips once each packet has been opened. My kit will expire one year and five months from receipt instead of the two years I should be able to expect. Is that a manufacturer’s problem or Amazon’s problem?And take a look at the two different charts enclosed in the kit. One is part of a leaflet of information, and the other is a “waterproof” sticker. You can see the two charts side by side and again with the wet test strip between them. Most of the color blocks in the test parameters are somewhat clear enough to measure within the chart, and between the two charts, to be able to accurately compare them to the test strip. Some of the color blocks, however, are ambiguous to the point that making an accurate comparison is impossible. I’ve contacted my local water office with questions about our water re to the questionable parameters. One that I know is terribly inaccurate is hardness. Our water is extremely hard, just by using several easy-to-discern metrics like staining, spotting, laundering performance, etc. The test strip, however, shows that our water is at the lowest level re hardness. There are other parameters that look questionable, too.Finally, in order to be able to access “YOUR FREE E-BOOK”, you must install Facebook/Messenger. No, thanks. This is an easy return.
