The Defelsko UTG M series digital ultrasonic Thickness Gauge is an ultrasonic wall Thickness Gauge with a multi-echo transducer, which can measure the thickness of the material through the coating without removing the surface coating.UTG M1Digital ultrasonic Thickness GaugebeThe standard model of the UTG M series features a high-resolution display with 250 data storage memory.The probe of UTG M1 is a 5MHz contact probe with a wear-resistant alumina probe with a measurement range of 2.50~125.00mm.


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
1) High-resolution LCD screen
2) With 250 data storage memory
3) It has two measurement modes: single echo and multiple echo
4)Flash indication – suitable for noisy environments
5) AdoptionImpact-resistant lenses andAbrasion resistant probes
6) Equipped with shock absorption, with clamp rubber protective holster
7)The calibration certificate (long) shows traceability to NIST
8) Comply with national and international standards, including:ASTM e797
9) Built-in temperature compensation to ensure measurement accuracy
10)Minute scans – measurement rates up to per second20 pcsreading
11) Statistics - Continuously display/update the number of mean, standard deviation, min/max thickness and thickness readings
12) There will be measurements that exceed the limit specified by the userHiLo alarm sounds and visible alarms
