How do PlantPRO and Bright Dyes water tracing products work?
PlantPRO and Bright Dyes water tracing products act as a coloring label on each drop of water. As that water or liquid travels, it can be identified at each point on its travel, until it reaches extreme dilution. Fluorescent dye tracers are dyes that selectively absorb light in the visible range of the spectrum. They are fluorescent because, upon absorbing light, they instantly emit light at a longer wavelength than the light absorbed. This emitted (fluorescent) light goes out in all directions. Most common fluorescent tracers are compounds that absorb green light and emit red fluorescent light.
