required for accuracy By mike on 7/8/2017mike wouldn't recommend this product to a friendHanna calcium test kit worked better when I bought this water. I thought it was worth a try since the results I was getting with my ro water where way off compared to other calcium test kits which I use.
Works well, accurately measures calcium By Aja on 3/11/2016Aja would recommend this product to a friendPersonally I found using this deionized water rather than distilled water, or the RO water I produce (0 TDS) provides much more accurate consistent results. I can't explain why, I called Hanna and they can't explain why.
However lets be honest pretty expensive as far as water goes thus the 4 stars.
