These dyes can be used for leak detection in areas such as drains, guttering, swimming pools etc. Their key advantage is that they are visible to the naked eye in very low concentrations (ppm levels). The fluorescent dyes can be detected at even lower concentrations using a UV lamp.

Typical application levels for these dyes are 10 ppm or lower. A sample is approximately 20g in weight and is sufficient for about 2,000 litres. 1 Kg of product is sufficient for about 100,000 litres.

If you are detecting leaks where drinking water is involved, we recommend using the food dye E133 Brilliant Blue FCF Granular.

If you are searching for leaks in a heating system, we recommend using Bestoil Pyranine 01.

If you are detecting oil leaks, we recommend using Bestoil Green FYG.

If you require UV detection equipment, please contact Glowtec Ltd who will be able to offer advice and supply the right equipment.
