System of the fluorescent penetrant <strong>testing</strong>.<br />
Present system correspond to requirements of world standards: MIL-I 25135E, MIL STD 6866, AMS 2644, EN 571-1. All<br />
components meet the European requirements on Health, Safety and Ergonomics. The inspection system is basically made of<br />
stainless steel and equipped with first class means for functional control, delivered by producers like Siemens, Rittal,<br />
Weidmüller, Festo, Sick, Balluf.<br />
