	Extending Rod, extending rod increases the depth for pickup to enter the part. Length of extending rod is 50mm.
	Right Angle Rod, change the position of the sensor, mostly use for measure surface of particular groove.
	Standard Sensor,to measure most of the plane, inclined plane, cone surface, inner hole, groove and other surface roughness, in addition to the standard sensor, other special sensors are needed to measure the measuring platform.
	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.
	Small holeSensor, to measure the inner surfaces of holes with radius more than 2mm, better to work with platform KA520 or KA620.
	Deep Groove Sensor,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, 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.
	Standard Roughness Calibration BlockMulti-engraved lines (Square Wave) Made by optical glass, with high hardness, high accuracy standard roughness value, anti-scratch, has longer life than metal roughness block. Meet standard GB/T19067.1-2003 and ISO5436-1:2000 Approximation: Ra=0.1um, 0.2um, 0.4um,  0.8um, 1.6um, 3.2um, 6.4um Customized Value and Sine Wave available, welcome to inquire.
	Standard Roughness Calibration BlockSingleengraved lines Made by optical glass, with high hardness, high accuracy standard roughness value, anti-scratch, has longer life than metal roughness block. Meet standard GB/T19067.1-2003 and ISO5436-1:2000 Approximation: Ra=0.1um, 0.2um, 0.4um,  0.8um, 1.6um, 3.2um, 6.4um） Customized Value available, welcome to inquire.
	Roughness Comparator  (30 pcs/set) This set contains standards of the six most important machining methods in the prevalent "AA" values. These surface roughnesses are used to compare and determine the degree of the surface finish by comparison method and eye estimation or magnifying glass. The surface rough contrast blocks is made of 45 super carbon steel except the GCr15 which is using to plat lapping the sample block. All 30 specimens are calibrated in u''AA (Arithmetical Average) and in the metric equivalents um Ra.
