Good buy, great company i had missing products and they sent me replacement pouches

😊👍

worked as the should , Hach has been around the water works industry for many years , of course their stuff is reliable

I have to use these every day to check the chlorine for our neighborhood water system. It’s a much better price than buying them through our well contractor.

The packets are what we need to tell the chlorine levels in our drinking water with in our community well
