Fluoride-only strips often get lighter in higher levels of fluoride. A benchtop photometer such as the HI83399 Water & Wastewater Multiparameter (with COD) Photometer and pH meter or the benchtop HI801 iris visible spectrophotometer would be great additions to any laboratory setting. The strips can detect fluoride and usually give you a range of how much might be in the water. Test strips aren't as accurate as photometers or reagent dyes. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws.
