Ultrasonic Thickness Gauge Model TT120
Features of TT100, TT120 & TT130
- Time ultrasonic thickness gauges measure the thickness of ultrasonic wave well-conductive materials with parallel top and bottom surfaces. They are also used on measuring wall thickness of pipes and pressure vessels to determine surface erosion.
- Model TT100, TT130 measures metals, aluminum, titanium, plastics, ceramics, glass etc. TT120 measures steel. TT120 can measure materials temperature 0º to 300ºC while other models measure materials temperature -10º to 60ºC.
- All models have the following functions: Measuring display in mm; automatic calibration; Automatic V-path correction; Coupling condition indication; Low battery indication; Auto shut-off. They all use 2 x 1.5V AA alkaline batteries. All come with a compact carrying case.
