Small hole Sensor
The groove sensor is the standard sensor of the roughness meter, and
its demension are as follows:
Small hole sensor can measure the plane, inclined plane, cone surface,
inner hole and other surface roughness.
Minimum measurable hole diameter:
Ф
5mm
The use of small hole sensors must be installed on the measuring
stand for measurement.
6
Extra small hole sensor
Using Extra small hole sensor, the inner surfaces of holes with radius
more than 2.5mm can be measured. Refer to the following Figure for
detailed dimension.
Extra small hole sensor operation method
The skid of the extra small hole sensor is behind the stylus. When it
contacts the workpiece, the pickup position is first high and then low.
The use of extra small hole sensors must be installed on the measuring
stand for measurement.
With deep groove sensor, it is possible to measure groove with width
wider than 3mm and depth deeper than 10mm, or the surface
roughness of step with height less than 10mm, Also can used to
measure the planar, cylindrical used with platform. please see figure for
detailed dimension.

Deep Groove Sensor

Support for flat surface
It is suitable for measuring the roughness of the measured object which
is smaller than the roughness tester and the measuring plane is plane.
The support can protect the sensor effectively.
