Use of Tropic Marin NP-Standard

The solution contains a precisely set nitrate and phosphate value (= set point). Instead of a water sample, you measure a sample of the standard. If the determined values ​​agree with the target values, the test reagents work. If there is a deviation of more than 50%, we recommend that you stop using the test. If there are minor deviations, you can determine a correction factor and continue to use the tests.
