New Way of Inspections
No paint removal
Integrated inspection workflows
Inspect more with less cost
Digital from start to end

EMA-3T is a electromagnetic acoustic transducer (EMAT) ultrasonic thickness gauge that is different from any other. It is designed with the core principles of Industry 4.0 in mind to bring efficiency to the inspection process.

EMA-3T integrates asset identification (Barcode & RFID readers), inspection workflows and connectivity (Wi-Fi & Bluetooth) all within a practical ergonomic design.

EMAT Technology

EMA-3T uses electromagnetic acoustic transducer (EMAT) technology to perform thickness measurements. This method allows significant advantages over standard piezoelectric thickness gauges for ultrasonic thickness inspections.

  • No paint removal required (non-contact up to 4 mm)

  • No surface preparation

  • No couplant required

  • Measures through unbonded paint

  • Sensor not required to be perpendicular to test material

  • Use in corroded areas

  • High temperature applications

Technology Comparison A

Asset Identification

  • Asset database can be directly imported to EMA-3T before inspection

  • Integrated asset identification technologies (RFID and Barcode readers) allow identification of each asset and loads pre-defined inspection workflow in 2-clicks

Inspection Workflows

  • Interface includes standard functions such as A-scan, B-scan and 3 standard inspection workflows: Line, Matrix and Pipe

  • Desktop application allows customization of workflows based on customer’s requirements

  • Large internal memory allows multiple datasets (asset database, inspection results and workflows) to be synchronized to EMA-3T



  • Data transfer options: USB cable, Bluetooth or Wi-Fi

  • Wi-Fi data transfer between EMA-3T and database can be exchanged simultaneously

Ergonomic Design

  • Slim handle to allow users to operate with just one hand comfortably

  • Inclined display to reduce strain on the wrist during long working hours

  • High resolution display to provide clear visibility in direct sunlight
