Water Tracing Dyes
Presto Dyechem is a leader in the manufacturing of water tracing dyes. Our Trace-A-Leak dyes are widely used for color identification of water systems. Some uses are: Leak detection in closed systems, plumbing tracing, septic system tracing, sewer drain studies, pond leaks, flow and rate studies and more.Trace-A-Leak dyes come in three colors:
Fluorescent Green
Brilliant Blue
Fluorescent Red
All three dyes are used as a visual detection. The fluorescent green and red dyes can be detected with an ultraviolet light or by a fluorometer while the blue does not have these characteristics. The dyes are safe and non-toxic, as well as biodegadable. Sunlight also breaks down the color. These dyes are used by public works departments, sanitary authorities, engineers, and many more to those who need to trace water.
