description
The LM-5 series ultrasonic thickness gauge utilizes ultrasonic measurement principles, emitting sound waves from one side of a workpiece to conduct real-time digital thickness measurements without requiring workpiece disassembly. As an ultra-compact measuring instrument, it delivers fast, non-destructive, and highly accurate results. Equipped with A and B scanning functionalities, its echo display enables users to better oversee measurement processes, expanding measurable thickness ranges, enhancing result precision, and mitigating material-related measurement errors.
It finds wide application across manufacturing, metal processing, aerospace, railway transportation, chemical, and commodity inspection sectors. Beyond precise thickness measurement of various plates and components, the gauge supports continuous monitoring of production pipelines and pressure vessels, tracking their corrosion-induced thinning over service life. It is an essential instrument for the nondestructive testing (NDT) industry.
