Fluorescein Liquid Dye RXSOL   is a commonly used dye for hydro test operations .Fluorescein Liquid Dye RXSOL   is a brown liquid which produces a red / pink solution once diluted in water. The solution then produces an orange fluorescence when excited with a blue or green light. For subsea detection of Fluorescein Liquid Dye RXSOL, an optimum excitation wavelength  should be used.

Normal dose for application is approximately 100 ppm. Rx Marine  can not stipulate an exact dose for Fluorescein Liquid Dye RXSOL . This is due to the strength of colour required being determined by a number of scenarios e.g. style and sensitivity of detection apparatus, sea bed depth and tidal currents. Generally, as a rule of thumb, the dye must not be dosed at below 100ppm for visual detection.
Detection of Fluorescein Liquid Dye RXSOL has been proven using the  Leak Detection Systems.
