Work in with Probes	Related Application
Standard Probe	When measuring circular workpiece less than 2CM in diameter,easily rolling, unable to fix instrument to measure,it is necessary to use measurement stand.
Groove Stylus	If the roughness of deep groove workpiece,or pedestal seat less than 10mm height in to measure, it is necessary to use the deep groove sensor with measurement stand.
Curvature Probe	When the surface of workpiece is curved,cambered,or uneven.Only curvature sensor can be used to measure the surface roughness.When measuring with stand.
