The Surftest SJ-220 portable surface roughness tester combines high accuracy and measurement speed with innovative features creating a new class leader in surface inspection.
The Surftest SJ-310 portable surface roughness tester is able to operate independently of mains power and make measurements on almost any part of a workpiece of practically any size.
SJ-411 has many innovative features combined with high accuracy and competitive price making this instrument the new leader in its class. It has a large touch-screen, color-graphic LCD and can be used for skidded and skidless measurement.
Our range of Surface Roughness Testers are ideal for rapid measurement of surface texture on metal or non-metal parts. A diamond stylus is drawn across the test surface by a motorized traverse mechanism. Vertical movement of the stylus across peaks and valleys is converted to a digitized signal and sent to a microprocessor where the parameters are instantly calculated.
