Industrial Test Systems WaterWorks 481108 Total Hardness Test Strip, 3 Second Test, 0-1000ppm Range, Our #1 Test Strip for Total Hardness, Bottle of 50 Tests, Tan

Easy to use and works well!

Have used this product before. Water hardness test strips work great!

We live full time in our motor home in a Central Florida where the water is notoriously hard. We have an On the Go portable water softener which needs to be regenerated about every two months.The Water Works strips (50 to a bottle) help us determine when to regenerate. The strips test calcium and magnesium hardness from 0-1000 ppm.The bottle also describes the effects of hard water at various ppm readings.The testing process is simple:1. Dip one strip into a water sample for 3 seconds without motion.2. Remove strip3. Immediately match to the color chart on the bottle within 1 minute.A diagram illustrates the process. After regeneration, the water will read 0 ppm. Over time, as the hardness increases, the color on the chart will increase. We typically regenerate when the strip reads 250.We trust Water Works strips to indicate when to regenerate our system.

Have used the product about 5 times before writing this review. Hey, it works as advertised and meets my need to know when the water is getting harder. Yes, I know I should be able to tell the change in hardness while I am using the water. But, for me, the gradual change in hardness is barely noticeable. Until the water is pushing 250+ in the hardness range. I like the product and the price. Will purchase again.

Results compare well with how with how long my water softener lasts on one batch of salt before needing a regen.

I used these test strips to test my new water softener, and plan to check the water every few months. I learned from the test strips and information I read that I had the water softener set too high, and that the water was too soft. I dialed the hardness setting back on the water softener, and the water still reads "soft", but the softener uses less salt, and the water is MUCH more comfortable to the skin. I guess if it's too soft, the pH gets low, alkaline, which can be corrosive to pipes and water heaters, and irritating (too drying) to the skin and hair. It makes a BIG difference. I think these strips are a great product for checking "hard" source water, and the "soft" treated water, not just to make sure the water softener is working, but to make sure you don't have it set too high. I was able to set my softener at a lower setting, and water still reads as "soft", and our skin and hair are not too dry. These strips could not be easier to use. Just dip for 3 seconds, and color match to determine the hardness of the water being tested. The instructions, hardness color chart, and hardness recommendations are all on the bottle.

Great product

Just got the package. Opened it up, read the directions, and tried it with water from the kitchen sink faucet. Compared the strip to the color chart. It was between 0 ppm and 40 ppm, which is almost no change in color. Package says this is "very soft". We have well water with a pretty good treatment system on it. I wanted to make sure the strips worked, so I got a cup of water straight from the well. Test strip indicates between 425 ppm and 1000 ppm, which the package says is "very hard". It's good to know that our softener system is working the way it's supposed to, and also to have a test kit to use when problems arise. I'm convinced that these strips work. I like the fact that the strips are in a screw-cap bottle with a dessicant package in it. Mine has an expiry date of 05/18.

These test strips do exactly what they’re supposed to—check water hardness. I use them regularly, and even though I was a bit skeptical at first, they’ve proven to be super reliable.They’re great to have on hand when I’m unsure about a water source. Quick, easy, and accurate. Definitely recommend if you need a simple way to test water hardness!

Ich messe damit stichprobenweise alle halbe Jahre die Wirksamkeit meiner Umkehrosmoseanlage für Gießwasser. Auch früher als Aquarianer habe ich solche Meßstreifen verwendet. Damals gab es noch nichts anderes. Aber auch heute noch funktioniert es besser als die digitalen Meßgeräte aus China, die nach ein paar Mal Benutzung schon kaputt sind. Meßstreifen funktionieren immer. Auch bei einem TDS-Meter hat man laufende Kosten für Kallibrierungsflüssigkeiten und das nervige Rekallibrieren, wenn so ein digitales TDS-Meter überhaupt so lange hält. Da sind die Streifen praktischer und zuverlässiger.

Great test strips that turn darker the harder the water is so an accurate way to set up your water softener. mine, in common with most if not all, regenerates against a given volume of water used, the hardness setting was factory set and nowhere near high enough to give me properly softened water. I re-set it to a high value and over a couple of weeks gradually reduced it to where it now delivers soft water and uses minimal salt. These strips are expensive, but so is salt.

Pratiche e precise. Le uso per testare il calcare in luoghi diversi quando viaggio. Attenzione che dopo la data di scadenza non reagiscono più e danno sempre indicazione di acqua non calcarea. Purtroppo scadono abbastanza in fretta.
