Fluorescent dye tracers are dye which selectively absorb light in the visible range of the spectrum. They are fluorescent because, upon absorbing light, they instantly emit a light at a longer wave length than the light absorbed. They can be easily detected visually, or measured using equipment. The dye tracers are economical, easy to handle, and are bio-degradable.
Standard formats are tablet or liquid concentrates.
Tablets Tablets are easy to use and handle. Each tablet, dissolved in 60 gallons of water will give a dye concentration of 1 part per million. Liquid Concentrate Liquid concentrates are available in handy gallon jugs. Each gallon should be added to 100,000 gallons of water to give a concentration of 1 part per million.
