The Electromagnetic Ultrasonic Thickness Gauge is a non-destructive testing (NDT) instrument that uses electromagnetic acoustic transducer (EMAT) technology to generate ultrasonic waves in test materials via electromagnetic coupling. This advanced system enables non-contact measurement without surface damage and is specifically designed for high-temperature applications and moving objects such as hot steel plates and in-service pipelines. With exceptional accuracy and rapid measurement capabilities, this instrument is widely utilized across petrochemical, metallurgy, aerospace, pressure vessels, pipelines, automotive manufacturing, and research applications.
Key Features
Easy to operate with intuitive controls
Compact, portable design for field applications
Mobile app and iPad connectivity for real-time waveform and thickness display
Low surface preparation requirements - measures on rough surfaces without grinding
Coating-insensitive - capable of measuring thickness through coatings
No couplant required - suitable for high-temperature measurements
A-scan mode for direct ultrasonic waveform viewing and verification
B-scan mode for comprehensive analysis

Maintenance Guidelines
Do not scratch the display with sharp objects
Avoid subjecting the instrument and probes to strong impacts or vibrations
Keep the instrument away from excessively humid environments
When connecting or disconnecting probes, hold the movable sleeve along the axis and apply force - do not twist the probe to prevent damage to the probe cable core
Oil or dust accumulation can cause the probe cable to deteriorate or break over time - clean the cable after use
