The SP-395N handheld NDSA fluorometer uses UV fluorescence to detect NDSA content in water, giving instantaneous, reliable results. This technology is not wet chemistry; results may vary depending on water sample quality, and background organic matter can cause a false positive reading. Accuracy is best in consistent makeup water quality with little organic loading and no known organic contamination.

Users should identify the correlation to exact wet chemistry values and account for potential background interference by checking untreated makeup water for UV fluorescence signal. The SP-395N will not work correctly in waters containing nitrite treatment, as nitrite absorbs UV light and causes a false low value.
