Users can select the suitable probe according to the thickness of the
work-piece to be measured.
U5.0: The probe is used common in many measurements, for example
when the measuring surface is flat or with huge curvature, or the
thickness of the work-piece to be measured is large than 50mm.
U5HT: Mainly used in the thickness measurement when the temperature
is less than 350
℃
U7.5: Mainly used in the measurement of thin wall thickness and
small curvature surface.
U10.0: Mainly used in the measurement of thin wall thickness and
small curvature surface.
U2.0: Mainly used in the measurement of coarse
particles such as cast
iron.
