Hanna Calcium Meter

[monocus]

the instructions are a little vague,but after a few tests i have no problem with it.the only problem is that i've spilt 2 bottles of the regent.all the checkers are different-an easy way to remember things is put a sticker on the ones that you have to hold the button on-makes testing faster.for the calcium i have the regent and salt water already in the syringes,the packet open and a large syringe with r/o water ready
