Water Hardness Test Kit-150 Strips Water Quality Testing 0-425 ppm

Works week and good price

My pool water was way too hard and using these strips I was able to monitor the level as I removed the calcium. I installed a water softener in the pool and the test strips let me control what was going on.

Easy to use, water hardness test kit. The kit works well provided the steps are followed according to the instructions. The test results completed as was expected. I am pleased with the kit overall.

shades of color between different levels of hardness are hard to distinguish.

Great for testing drinking water. Water is clearer now. These are not great for testing pool water. Neighbor was using these. I explained how these are used. His pool looks good now. Bought a pool kit.

This is your average water testing stripe.

I bought these hardness test strips to help program the settings for my water softener and then to verify it is working properly. These are very easy to use - just dip in water for 2 seconds and then wait 30 seconds to check read the color change. Does what it's supposed to do, no complaints.

Perfect test strips

très bien

I use tankless water heater and it's paramount that the water be soft in order for it to work properly. These strips are easy to use and you get the result right away very convenient.
