How to Use Fluorescent Dye Leak Detectors in Systems

What can help identify leaks over time in various systems?

a) Special lubricants
b) UV lamp
c) Water sealant
d) None of the above

Answer:

b) UV lamp

Fluorescent dye like fluorescein can help identify leaks over time in various systems. When the dye is used in a system, it will spread throughout it. If there is a leak, the dye will start to appear in the location of the leak after some system operation. This makes it easier to spot leaks over time.

A UV lamp is required to locate a small leak with fluorescent dye. The UV lamp causes the fluorescein dye to “fluoresce”, or emit visible light. This enhances the visibility of the dye and helps in locating small leaks that may be difficult to notice under regular light.
