	KS90 - Right Angle Rod, change the position of the sensor, mostly use for measure surface of particular groove.
	KS100 - Small Hole Sensor, measures flat surface, shaft ; when measure inner hole surface, the diameter of inner hole are required>5mm, depth>22mm.
	KS110 - Curved Surface Sensor, to measure smooth cylindrical surface which radius is larger than 3mm, for the large radius smooth spherical surface and other surface also can obtain good approximation, need to work with platform KA520 or KA620.
	KS120 - pinhole Sensor, to measure the inner surfaces of holes with radius more than 2mm, better to work with platform KA520 or KA620.
	KS130 - Groove sensor, measure flat surface, or groove surface with width ≥2mm, depth ≤3mm, or step down ≤3mm deep, also to equipped with Measuring fixture, can measure cylindrical surface.
	KS131 - Deep Groove Sensor, measure groove with width wider than 3mm and depth deeper than 10mm, or the surface roughness of beneath steps with depth less than 10mm, also can used to measure the planar, cylindrical used with platform,better to work with platform KA520 or KA620.
	KA520 -Metal Substrate Working platform, adjustable height 200mm. With flexible and stable operation and wider application range. Roughness of complex shapes can also be measured. Measurement stand enable the adjustment of the position of stylus to be more precise and measurement to be more stable. If Ra value of measured surface is relatively low, Using measurement platform is recommended.
	KA620 -Marble Substrate Working Platform, adjustable height 300mm. With flexible and stable operation and wider application range. Roughness of complex shapes can also be measured. Measurement stand enable the adjustment of the position of stylus to be more precise and measurement to be more stable. If Ra value of measured surface is relatively low, Using measurement platform is recommended.
