BRIGHT DYES Fluorescent Water Tracing Dyes

Ecologically safe dyes for use in stream tracing, lake studies, flow mapping, storm and sewer analysis, pollution studies and leak detection. Two formulations: FWT Red, a specially formulated version of the dye Rhodamine WT and FLT Yellow/Green, which is a formulated version of the dye Fluorescein. Fluorescent colors can be detected visually in most water conditions or with the use of ultra-violet light or a fluorometer.

Fluorescent dyes are temporary and will degrade naturally in sunlight, 2 - 5 days for Red and 5-7 days for Yellow/Green, or with the addition of chlorine. FLT Yellow/Green is resistant to absorption in organic matter and should be used in water with heavy sediment loads.
