There exists standardized, recognized methods for testing water parameters, basically a committee of experts sits down and comes up with the best method of testing, say, alkalinity. They publish the "recipe" for the test, including how to prepare the reagents, what quantities to use, what interferences you may see, etc. They put all the recipes in a huge book.

Anybody in the world who then wants to test for alkalinity looks in the book, follows the steps, and is certain he is measuring alkalinity, with whatever percentage of accuracy and precision, knowing to look out for whatever interference.

If you're working in a water filtration plant and testing something as critical as drinking water from the filtration plant, you better be sure your methods are approved and recognized. (And that everybody there tests the same way so the results are all interpreted the same way - unlike the pool stores.)

The book is called "Standard Methods for the Examination of Water and Wastewater", the committee is called the American Water Works Association.

The tests found in Taylor products follow, almost to the letter, these procedures.

What this means is that you're sure that, if you follow the instructions, the test results are accurate, precise and repeatable.

The same cannot be said for test strips.
