hole probe, tooth surface probe, small pillar, height adjust platform, extension bar, lateral transfer rod etc.Standard ProbeThe standard probe is the most frequently used probe. It can meet most of the surface roughness measurement, such as plane, slope, conical surface, the inner hole, the groove and other. It can do convenient hand-held measurement. Except the standard probe, other probes require the use of special measuring platform to measure.
 Curved Surface ProbeSurface probes are used to measure smooth cylindrical surface roughness with greater than 3mm radius. Even larger radius spherical surfaces can be achieved the desired approximation. The larger the curvature radius, the better the testing results.Deep Groove ProbeDeep grooves probe is similar with standard one. The only difference is the deeper depth. It can measure the roughness of the most flat, slope, conical surface, the inner hole, the groove and other surfaces. Deep groove probe cannot be used for hand-held measurement, the other probes require the use of special measuring platform to measure.
Small Hole Probe
Small hole probe is used to test the inner surface of the hole which is larger than 2.5mm diameter, other functions are the same as the standard probe.
