weAQUA Water Hardness Test Kit - DoubleCheck 50 Strips - Hard Water Test Kit – Tests Calcium, Magnesium (0–425 PPM / 0–25 GPG) – for Home & Professional Use, Tap, Pool, Spa, Dishwasher

Great bit of kit. Excellent value in my opinion. Bought to check my future whole house filter installation. Checked incoming tap Hard. Checked Brita filtered water Soft. Works 👍

Absolutely brilliant product. So simple and quick to use. Tested that the plumber had connected outlets correctly. We have various taps, some are fed from the water softener, some not. This enabled us to check that everything was in order. Very clear, easy to see result. Astonished at how well it works. Thank you. And of course quick delivery by Amazon too.

They work as they shouldand are accurate! I turned off my water to my water softener and took a sample after running the water for a couple of minutes and tested the water and it showed it was very hard, I repeated the test with the softener on and after running the tap to clear the hard water - see the results on the photo, so in my opinion thru are very good value for money!

Although a bit expensive but did the job

The testing strips give a satisfactory indication of water hardness/softness. So for the price they are okay. So what’s wrong? Well the problem is that once opened all fifty have an expiry date and this is only three months hence! Had I realised this I would not have bought them. It would seems that some other reviewers feel the same. I think the manufacturers should really highlight this in the item specification.

Excellent test strips now i know the harness i can set the dishwasher correctly

I wanted to confirm my water softener was doing the job. easy to use and the instructions were simple. results in under a minute.

Item as described and arrived quickly

These strips work great. It allows me to test the hardness of my water before and after my water softener to make sure it’s working properly. I had some issues with the water softener. I was able to use it to troubleshoot my system. They are easy to use and read. Will buy again if needed.

Excelente kit, cumple cabalmente lo descrito, mide la dureza en 2 segundos. Recomiendo ampliamente el producto.

These really work! And much better than I expected for test strips! I wanted to see if my 27 year old water softener is still working properly. I tested bathroom water and kitchen water that bypasses the water softener and the results were very clear and easy to read.

Very accurate and easy to use. The test strips confirmed the hardness readings on my water quality meter. The only negative is the short expiration of only 3 months after opening. Wish the test strips were individually wrapped to have a much longer expiration. If the test strips were individually wrapped, I would give it a 5 stars. I tested our outside water from 3 different locations and one from inside the house from the bathroom sink faucet. All outside water tested hard to very hard as expected and inside water tested soft since we have a water softener.

Worked as accurately as the plumbers test kit. I did these strips right next to the expensive kit my plumber had and the results were identical! Unbelievable for $5
