In the year 2007, our company launched the handheld High Precision Ultrasonic Thickness Gauge UM-3 with a single crystal delay line probe. The 15 MHz single crystal delay probe is used to improve the accuracy by using multiple echoes, so that the resolution can reach to 0.001mm and the lower limit of measurement can down to 0.30mm. UM-3 has two working modes: normal and precision. The normal mode adopts the interface wave-echo method, and the measureing range is 1.5mm～20mm; the precision mode adopts the echo-echo method, and the measuring range is 0.30mm～10mm.
Performance of UM-3 Thickness Gauge
1、High Precision, 0.001mm Resolution
2、Suitable to measuring thin materials, and measure to 0.25mm flat metal sheet accurately and reliablely
3、Through coating function, it can through like the skin of paint, and no need to polish the paint on the material
