STANDARD SENSOR
The standard sensor for this instrument is the small hole sensor, it can directly measure roughness for flat surface when this flat surface size is greater than the main unit with sensor, otherwise we recommend combination with KA520 or KA620 platform or any other suitable height adaptor. Also note leveling is important.
