Review on Hanna Instruments HI38033 Total Hardness Test Kit by Dragan Nelson

I wanted to test the water to make sure the softener was still working. The kit was easy to use, signs of discoloration were clearly visible and the process was straightforward. Lost 1 star because you couldn't get a test kit for home use, it was clearly packaged for professional use but still easy enough for a homeowner to use. I have tested the water, confirmed the softener settings, verified that the softener is working and now I have 97 uses left.
