The SR100 portable surface roughness tester is powerful, accurate and easy to use.
The SR100 can measure roughness almost anywhere.  It is ideal for checking large components,
structures, auditing batch production prior to shipment and production line process control.
The innovative SR100 separates into two pieces to measure surface roughness.
The bottom half of the SR100 contains the traverse mechanism and stylus pickup assembly
which is placed on the surface to be measured.  Its wide base ensures stability.
The upper half includes a large LCD display, start button, mode and parameter buttons,
comfortably hand-held for easy operation and clear viewing.
A diamond stylus is drawn across the part, the motorised traverse mechanism is cam driven to
ensure that the correct horizontal distance is traveled.
Vertical movement of the stylus as it travels across peaks and valleys is detected by a piezoelectric
pickup which converts the mechanical movement of the stylus
into an electrical signal.
The electrical signal is digitized and sent to a microprocessor where the parameters are
calculated using standarised algorithms.
