1, 0.1mm Resolution.
2, Memory Function: 5 arrays are divided to store 500 thickness values.
3, Minimum Value Checking: Move the probe along the surface of the testing material, UM-1 is able to automatically find the thinest point.
4, Warning Function: If the measured value exceeds the pre-set thickness limit, the warning tone will start.
5, Two thickness units of millimeter and inch are supported.
6, Two language interfaces of Chinese and English are supported.
