SimplexHealth Total Hardness Water Test Strips (10 Strips) - 3 Second Testing - 0–1000ppm Test Range - Fast & Accurate

I bought these test strips to check the water hardness for my coffee machine, since I use a water filter and need to adjust the settings according to the hardness level. They were very easy to use and gave clear results quickly. A practical and useful product if you want to properly maintain your coffee machine and set up the filter correctly.

Very easy to use. Gives instant result. Although the bands of hardness are quite wide, so you won't be able to get a specific measurement (there are other kits available for this). The other thing to know is that Water Hardness seems to be measured in several different units. I used Copilot to convert the reading from this kit (ppm) to what my Bosch dishwasher wanted me to tell it.

Really good kit. The water in London is very hard, and I needed to test it to check if my filter was working. These strips are very useful, they’re easy to use .

Got the package super quick! Simple to read instructions on the outside with a key to follow I knew the water was hard around the London area but wanted to check how much so got this kit as Mrs was saying she was reacting to the water Put some water into a small glass/container don't put the stick under the running tap as it rubs the minerals off the stick too quickly! Dip the stick into the water for 3 seconds and hey presto it'll change colour which you can match up using the key I'll looking to take it elsewhere where someone has a softener or the water is softer generally to see if it does read correctly! Watch the video for a quick demo!

Bought to reset water hardness in my coffee machine and the worked very well

The product details that this only tests for calcium level change when it is not the only chemical that will affect the water hardness.

Kind of hard to see the exact value but at least I know my water softener is definitely working

Excellent Product

Kit che funziona bene e i risultati sono validi. L'ho provato in due posti diversi con durezza notoriamente diversa ed il risultato del kit lo dimostra. Per quel che costa è utile per capire la situazione di durezza dell'acqua

La cantidad que viene muy bien, muy fácil de usar y ya he analizado las aguas de mi zona y puedo elegir la de menos cal. Muy bueno

Robi co ma robić, duża skala, łatwe odczyty

Voor de koffiemachine wil ik de juiste instelling van de waterhardheid weten. Met deze strips kon ik in een paar tellen de hardheid bepalen voor de juiste instelling. Eenvoudig in het gebruik door simpelweg een kleur op de verpakking met de strip te vergelijken.

Très bien
