Digital Ultrasonic Thickness Gauge with ±0.1mm Accuracy for Pipeline Corrosion Monitoring
Designed for fast, non-destructive, and precise assessments, the ultrasonic thickness gauge works with metals, high-temperature pipelines, plates, plastics, glass and other materials. It serves as a critical material protection tool for manufacturing, metal processing, chemical, commodity inspection sectors, and tracks corrosion-induced thinning of pipelines and pressure vessels in production equipment.

description
Our factory-engineered LM series digital ultrasonic thickness gauge utilizes ultrasonic measurement technology and features a compact, ultra-small footprint. This instrument enables fast, non-destructive, and highly precise thickness measurements, and is widely deployed across manufacturing, metal processing, chemical, and commodity inspection industries. It is optimized for materials that allow ultrasonic waves to propagate uniformly through their structure and reflect off their back surfaces.
In addition to delivering accurate measurements of plates and machined components, this gauge monitors pipelines and pressure vessels in production setups to track corrosion-related thinning over service life. It stands as an indispensable specialized instrument for material protection and integrity management.
features
Measurement Error: ±0.1 mm (for thickness 10 mm) *Note: H represents the thickness of the test object
Coating Penetration Function (Exclusive to LM-1D)
Operating Principle: Utilizes the pulse-echo method with a dual-crystal probe
V-Path Correction: Compensates for the nonlinearity of bimorph probes via sound path correction
Minimum Thickness Scanning: Automatically detects and measures the thinnest section when the probe is dragged across the test object’s surface
Optional Software Support: UmView software enables transmission, storage, analysis, and documentation of measurement data
