Portable Surface Roughness Tester SHT-180
Brief Introduction:
Portable surface roughness tester used to measure surface roughness
of various machinery-processed parts, especially for roughness
measurement of complex parts, such as: Flat, Curved surface,
Grooves and Holes.
Capable of evaluating surface textures with a variety of parameters
according to various national standards and international standard.
The measurement results are displayed digital/graphically on the
LCD, and output to the printer.
