I would hold on this. By Dan on 9/4/11

Dan would recommend this product to a friend

it requires extremely pure water (DI/distill lab grade) and accurate measuring of 0.1ml (yes one tenth ml) of your sampl tank water. If you can get both right test will work. If your DI will have slight trace of CA you'll be way off.. according to Hanna even 2ppm of CA in DI is not acceptable. I would wait for Hanna address these issues.
Easy to use and gives accurate readings By Tom on 8/24/11

Tom would recommend this product to a friend

Easy to use and gives accurate readings. 2 things to note are:

- Requires DI water
- Reagent B is a powder

Not very happy about using a powered reagent, But other than that, I'm very happy with my purchase.
