It doesn’t seem to work properly.

No, the Iodine checker is does not span in the range of proper reef tank levels. This was a huge disappointment as popup advertised as suitable in aquarium category. When I called I was told I would have to pay for shipping back for a return. Also, in using the other checkers I have for testing the 10ml line does not match an actual 10ml volume. I have tested this with 10ml multiple syringes as well as a laboratory pipette. I would think Hanna would have noticed this touting a reputation for precision. The Customer service was friendly but no bending policy for customer satisfaction.

A full refund would have been the right thing to do.

The Hanna TDS tester is great, while the pH tester is a complete joke.
