AMT211 Professional Surface Roughness Tester Profilometer


AMT211 Professional Surface Roughness Tester Profilometer

Sensor can work in the meter, also can work independent through 1.0m length cable. (max can be 3m)



Portable Surface Roughness Tester AMT211 is a high accuracy instrument for measuring surface roughness. It can be used on variety of machining parts and operates on various surfaces, not only flat but also outer cone, outer cylinder, curved, pinholes, grooves, recesses grooves and axle etc. 

The AMT211 complies with international standards ISO, DIN, ANSI, JIS. 



Portable Surface Roughness Tester AMT211 allows surface roughness measurement both on metal and non-metal workpieces. It is suitable for machining and manufacturing, quality control, inspection departments, especially for measurement on large and heavy workpiece, assembly line on site. The AMT211 is a Non Destructive Testing instrument, damage won't caused to testing piece.
