時代TT120超聲波測厚儀是集當代科技電子技術和測量技術于一體的、XJ的無損檢測儀器，采用微電腦對數據時行分析、處理、顯示，采用GAO度優化的測量電路，具有測量精度GAO、范圍寬、操作簡便、工作穩定可靠等特點。TT110超聲波測厚儀可對各種板材和加工零件作精確測量，廣泛應用于石油、化工、冶金、造船、航空、航天等各個領域。
TT120超聲波測厚儀基本原理
探頭發射的超聲波脈 沖到達被測物體并在物體中傳播，到達材料分界面時被反射回探頭，通過精確測量超聲波在材料中傳播的時間來確定被測材料的厚度。
TT120超聲波測厚儀主要功能
自動校對零點，可對系統誤差進行修正；
非線性自動補償，利用計算機軟件對探頭非線性誤差進行修正，以提GAO測量準確度；
設有耦合狀態提示、低電壓提示、自動關機等功能。
