Lupo Premium Hardness Test Kit | Accurate Quick Test Strips for Measuring All Water Sources | 0-425 ppm (Calcium Carbonate) | Large Pack: 175 Strips

Very happy with my purchase. Super easy with clear instructions to follow to test water hardness.

The product serves its purpose well. It helped me identity the hardness of water at my new place. The strips are easy to use and has very clear instructions how to use. The only complaint I have is the quality is way too much, I barely used 4.

A lot of the test pads came loose from the plastic strips.

I tested my treated water vs untreated and the stops work very well and you can tell just how hard the water is by the color chart provided. Great buy.

The color chart is right on the bottle making the ease of use a great value for the money. The performance is great and gives results within 30 seconds. The bottle is water resistant so you dont get all of the test strips wet if you drop it in water accidentally. Good test kit!

I live on a well and have extremely hard water. I installed a new water softener and needed to test my water. Tested it 3 times and it didn’t move off of the first strip color. Took a water sample to a testing facility and my water is hard so these testing strips did not work. May be great for pools but not house water. Waste of my money.

To be honest I’m not sure because the last time I bought keto strips it was long ago but it’s hard to tell in what stage of ketosis I am, specially it the last three colors. I don’t recall having the same problem before but to be fair I’m not sure.

Works as described. Used it to test my water softener.
