We test in labs and also in site
The visual examination is performed in our / customer lab facilities as well as in site. Boroscopes with turning prism are used for standard testing inner spaces with direct inputs. Inspection of inner spaces with indirect inputs is provided by videoscope iPLEX with changing objectives. We have several sets of testing gauges for welds, photographs MSS-SP-55 and replicas SCRATA (according to ASTM A-802) for evaluation of alloys and industrial endoscopes, all for processing of VT testing.
