- Fluorescent water tracing dyes.
- NSF certified for use in potable water.
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, a formulated version of the dye Fluorescein. The fluorescent colors can be detected visually in most water conditions or with the use of ultraviolet light or a fluorometer.
The dyes are temporary and will degrade naturally in sunlight (2–3 days for Red and 5–7 days for Yellow/Green) or with the addition of chlorine. Yellow/Green is resistant to absorption in organic matter and should be used in water with heavy sediment loads.
