Our customer is an independent UK-based company that carries out inspection of heat exchanger plates for cracks and holes that penetrate the plates. They were using an oil-based fluorescent penetrant to carry out their inspections, but a water-based penetrant would be better practise, given that they carry out a high proportion of work for the food and drink processing industry.

The customer trialled two of our water-based penetrant products: MAGNAFLUX® FP-10 and AUTOGLO® AL-4B. With the AL-4B, the results were perfect;  the product was easy to use and gave clear indications under
UV light.
