Spectroline dyes reveal leaks in static and circulating water systems, boilers, storage tanks and other high-volume containers. The fluorescent dyes also are effective in locating leaks in piping, valves, condensers, seams, welds and fittings. To find leaks, users add a dye into a system and allow it to circulate. Wherever the water escapes, so does the dye, which remains at the site. When the system is scanned with a high-intensity UV lamp, the dye glows to pinpoint the leak’s precise location. WD-801 makes leak sites fluoresce blue; WD-802 reveals leaks with a bright green color; and WD-803 dye pinpoints them with blue-green.
