Leaks: red alert

In many industries, UV leak detection, which uses fluorescent additives and a blue (450nm) UV light, is well established as a reliable way to pinpoint escaping fluids.

However, many substances used in hydraulic and automotive systems naturally fluoresce yellow under UV light, the colour of some leak detection dyes. A fluorescent red dye from Spectroline is said to solve the problem of 'false positives' from oil, grease and hydraulic fluid, due to its colour. Available through Advanced Engineering, the range of dye formulations and colours offered enables bespoke combinations and fault-finding regimes for a range of applications.
