Hanna Calcium Checkers

Has anyone tested using various test (elos, salifert, hanna) and then sent the same sample off to a proper lab? That's the only way I'd agree with someone saying which one is "right".

ya, 10 years ago RHF did a comparason, sailfert and elos were the better ones, sailfert for some and elos for others, hanna was consistantly off.

10 years ago Salifert was the only one that looks the same as it does now. I didn't hear about Elos until 2006 ish when it became the new "best" test kit. Hanna has been using the colorimeters for ages, but the Checkers are still relatively new. I don't think the Checkers have been looked at that closely.

We are talking about the digital Hanna Checkers compared to the Elos and Salifert drop test kits. I actually wasn't aware that Hanna put out a drop test kit.
