Features:

  • UM-3 precision ultrasonic thickness gauge adopts single element delay line probe, improves accuracy by multiple echoes, the resolution up to 0.001mm ,lower limit of measurement to 0.30mm.
  • UM-3 has both common and precision operating modes. The common mode adopts the interface wave-echo mode,the measuring range is 1.5mm - 20mm; The precision mode adopts echo - echo mode, the measurement range is 0.30mm- 10mm.
  • High Precision, 0.001mm Resolution
  • Lower limit of measurement to 0.30mm
  • Through coating function, it can through like the skin of paint, and no need to polish the paint on the material
