 AUT400 thickness gauge (with A-scan Snapsot)
  • UM-4 ultrasonic thickness gauge made by our factory with OLED true color,built-in A-SCAN snapshot is a kind of high precision,

    new-type, and portable industrial nondestructive testing.The A-SCAN snapshot function can help users better control

    measurement and avoid the inaccurate measurement value leaded by the factor of material itself

    Shining Features:

    1.The industry's first economic and digital thickness gauge:

    2.Innovative A-scan snapshot function marks economic thickness gauge into the digital times:
    3. With the breakthrough zero measurement technology:
    Based on digital technology,with zero measuring technology, the thickness measurement value cannot be effected by ultrasonic intensity,material reliability.
    4.The only one with clear bright OLED true color screen of the grade product :
    5.More practical function


    white on coupling Diff/RR% mode Min./Max.mode red on alarm
    6.The only gauge real up to 0.01mm resolution among the grade product:
    UM-4series gauge can reach 0.01mm by adopting breakthrough digital technology and special algorithm. And experiments have shown it can

     easily distinguish the two test blocks of thickness difference of 0.01 mm
