Dye Tracers

  • Safe
  • Non-Toxic
  • Biodegradable
  • NSF Certified
  • EPA Approved

Choosing a product color:

  • Choice of color should be based on contrast to the background color of the water body. For instance, FWT Red offers greater contrast to heavy concentrations of algae.
  • Fluorescent FWT Red and FLT Yellow/Green because of their fluorescent nature have a greater apparent contrast than non-fluorescent blue.
  • For fluorometric testing use fluorescent FWT Red 200, it is more easily detected by fluorometric equipment.
  • Fluorescent FWT Red and FLT Yellow/Green may also be detected visually with a simple hand-held laboratory black light (UV) at significantly lower levels - in the range of 10ppb.
  • Blue is frequently used for decorative effects, evaluation of household systems, and generally where the blue may be more acceptable to public view
  • FLT Yellow/Green disappears in sunlight more rapidly than Fluorescent FWT Red and non-fluorescent Blue.
  • All colors are resistant to the absorption of suspended matter.
