Quest TruTec's proprietary technology, LOTIS® (internal) utilizes laser profilometry to inspect the internal surface of tubes in many critical applications such as steam reformers. Coupling this technology with patent pending reporting software, Quest TruTec provides immediate and accurate data to enable instant risk-based decisions. LOTIS has become internationally recognized by the NDT industry and the American Society of Nondestructive Testing (ASNT) as a time-proven NDT method. When catalyst removal is not indicated, tube inspections utilizing Quest TruTec's External Tube Crawler can be performed.
