Quickly pinpoint the exact source of all water leaks. Spectroline WD-801 and WD-802 water dyes detect all leaks, including those that were previously undetectable. Their bright glow under a high-intensity Spectroline UV lamp shows you the exact source of even tiny, evaporated and condensation- covered leaks.

Ideal for both new and existing equipment. WD-801 and WD-802 are effective on all types of water systems, both static and circulating, such as boilers, heaters, pumps, sprinkler systems, storage tanks, pipes and associated fittings. Typical applications include flow-rate measuring, invisible marking, and the testing of seams, welds, seals and fittings.

As easy as 1, 2, 3! 1) Pour the dye into the system. 2) Circulate or mix the dye. 3) Scan the system with the UV lamp — the bright glow lets you see all the leaks.

Spectroline dyes are economical. The suggested dilution ratio is one pint of WD-801 or WD-802 per 1,000 gallons of water, at a total cost of just pennies per gallon. One-pint containers are stocked; larger size containers are available on special order.

Choice of fluorescent colors. Choose WD-801 to have leaks glow blue and WD-802 for a green glow. WD-801 is invisible to the naked eye and WD-802 has a slight visible cast.

**WD-801 dye should be used only with UV lamps.
