No couplant required. Electromagnetic ultrasonic thickness gauge that can measure over coatings.
The EMAT WIFI is an electromagnetic ultrasonic (EMAT) thickness gauge that allows for thickness measurement without the need for couplants. Unlike traditional ultrasonic thickness gauges that require the application of couplants, this device enables thickness measurement simply by placing the probe on the measurement target, thereby improving the efficiency of inspection work. It can measure materials with paint, scale, or slight surface roughness, significantly reducing the need for pre-treatment. Additionally, it is equipped with WiFi communication capabilities, allowing for the confirmation and management of measurement data and waveforms in conjunction with smartphones and tablets. This facilitates smooth sharing of measurement results and data management on-site. It is ideal for measuring wall thickness and conducting corrosion inspections in plant equipment, piping, tanks, and steel structures. This product contributes to the efficiency and reliability of thickness measurement in the field of non-destructive testing (NDT), such as maintenance inspections and equipment diagnostics.

Applications/Examples of results
- Measurement of wall thickness of pipes and tanks in plant equipment, chemical plants, and refineries - Measurement of base material thickness from coatings and linings (inspection of anti-corrosion coating equipment) - Thickness measurement and corrosion monitoring of equipment with remaining rust and scale - Regular maintenance inspections of power plant equipment and boiler piping - Screening inspections of steel structures and large equipment - Verification of wall thinning and corrosion conditions in factory equipment and piping lines - Thickness measurement of metal structures such as bridges, steel structures, and ships - Efficient inspection of numerous measurement points in large-scale equipment Using the EMAT method, measurements can be taken without a couplant, allowing for confirmation of base material thickness even with remaining paint or rust, thus reducing the need for pre-treatment and enabling quick multi-point measurements. This technology is utilized in sites where rapid screening inspections are required, such as large-scale plants and equipment inspections.
