The Defelsko Positector UTG M3 Ultrasonic Wall Thickness Gauge is available in:UTG M series premium models, comparedThe UTG M1 adds more features to enable 10W of data storage, which not only transmits data wirelessly, but also displays graphs in real-time for easy data analysis.The transducer of the UTG M3 Ultrasonic Wall Thickness Gauge is a 5MHz contact multi-echo probe with paint coating penetration to measure material wall thickness without removing the coating.The thickness range of UTG M3 is 2.5~125mm.

1) High contrast color LCD screen
2) A-scan with adjustable Gain and screenshot function for further analysis and recording
3) B-scan, which shows the cross-sectional profile of the test material
4) It can store 100,000 measurement readings, up to 1,000 batches
5) Store thickness, profile and environmental measurements in a single batch
6)On-screen batch annotation, add annotations, variable batch names and more with the new built-in QWERTY keyboard
7) WiFi Technology - Wirelessly sync to PosiTector.net, download software updates, and connect to mobile devices for more extended features




The UTG M probe has a paint permeability that allows for fast and accurate measurement of the thickness of paint-coated metal materials without the need to remove the coating. It is also ideal for measuring blasted materials or other coating applications that require a long-lasting, wear-resistant contact surface.
1) 5MHz contact probe with abrasion resistant alumina probe
2) Multi-echo technology to achieve an average of 3 or more echoes ensures accurate and reliable readings
3) This is an accurate measurement method to measure the wall thickness of paint structures because it automatically ignores the coating, reducing inspection time and cost
4) Different echo modes can be switched freely
- Multi-echo mode can eliminate coating thickness
-Single echo mode detects pits and defects and increases the measurement range
