SimplexHealthTotal Hardness Water Test Strips (10 Strips)

Tested either side of a water softener the results were obvious and massively different (2-25) The tests are simple to use and easy to read. (Dip them in a clean container of water, or no more than dripping running water.) Excellent value.

As mentioned by someone else. the strips should not be placed under running water as the chemicals on the end of the stip that provide the reading can be washed off. Instead run the tap and fill a glass of water, then simply dip the end into the water; you will get an instant reading.Others have moaned about the colour chart and that it is difficult to discren some colour changes against the range printed. To be honest it is good enough for what you would use this for. If you are after a calibrated measurable device to measure water hardness then perhaps this is not for you.

Providing the instructions are followed the strips react well and give accurate readings.

Tested cold and hit from softener and pure filtered from main and these strips seemed to report the right result. Both hit and cold showed yellow ie soft and pure showed bronze ie hard. Great. Shows the softener is working correctly. Recommended.

Works perfectly has helped us set up our new dishwasher.

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

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

Happy with product, disappointed with my water softener. Live in Kent, tested incoming mains shows 250 ppm, after softener shows 120ppm. Looked up on local water company website, they state hardness for address is 261, so kit is spot-on but wish for softer water....
