—Keeping the tests user friendly was a big concern for us and our chemists were able to get the magnesium test to two steps only. Having clear color changes in the titration was also key, to help eliminate user confusion on guessing if they are reading the test accurately.

Each test uses a two-part chemical reaction and a syringe to add water until the final color is hit. We also guarantee you’ll get 50 tests out of each magnesium test.

In theory we are using the same ideas as in Ca test. The chemical solution here is very sensitive to PH and therefore we need to use a strong buffer.

Not as in the Ca test, our challenge here is to precipitate the Ca first and then find Mg levels. Our way of testing Mg is a bit different and based on direct titration where we add sea water to the chemical solution.

A special correlation table where we can correct Mg levels by knowing Ca levels without the need to precipitate it. Our ability to produce in small batches is critical to achieve analytical calibration which is a key to our tests accuracy.
