Product Description
Portable Surface Roughness Tester with Roughness Comparison Block and Chart
Advanced Portable Surface Roughness Tester SR-300T 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.
Application:
Portable Surface Roughness Tester SR-300T 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 SR-300T is a Non Destructive Testing instrument, damage won't caused to testing piece.
The stylus drive unit can be stored within the main unit for standard measurement, or separated from the display unit by using the supplied cable which allows more flexible measurement in any orientation. The driver can be separated and reattached in one simple step
