USA Made Total Water Hardness Test Strips 0-500 ppm for Water Quality Tests [100 Strips in Moisture Wicking Bottle]

These are very good and accurate and the case keeps them dry. I us them for my water Softner just too make sure it is still working.

I have been happy with this item and have compared it to other water hardness test strips that I have and the readings are consistent. This type of product is not going to give you a precise degree of water hardness, and that's basically the same that you will get with competing products. The colors are a bit hard to read and on none of these test strip products do the colors you see on the test strips look exactly like the reference pictures on the container. Thsese test strips, like their competing products, are good for telling whether your water is SOFT, Medium Hard, or VERY HARD. Distinctions between these readings are probably better done with a chemical titration system using liquids test agents, or perhaps an electronic reader (not sure of the latter).

I purchased these to check our water softener is working OK. I know the hardness of our water and the indication from these strips agreed when testing it. Our softened water showed up correctly as well. I'm happy.

We use these strips to help us determine the hardness of water passing through our motor home water filtration system and have found them to be very beneficial. 100 strips per package allows us enough quantity to test our water as we travel the country as well as our home. Pull water from the tap or hose and dip the test strip into the water and read immediately. The side of the bottle contains a read out that you match to the strip color to determine the hardness of the water. This is a very simple test strip to use, easy to read, and the hardness of the water matches the comparison tool well. We have felt very successful in using these test strips.

Works as expected for this type of tester. Gives you a general idea of water harness. I have a water softener and test showed close to 0 ppm scale, then tested outside water and it showed in the 125ppm range, so clearly the softener is doing its thing which is really all I needed to know. If you need definition to something like 20 vs 25ppm none of these strip testers will do that - you need a much more expensive test kit.
