SR300 and SR400 Surface Roughness Tester
These new editions of Starrett Surface Roughness Testers incorporate a large
display with the simplest of menu structures and the most up-to-date
parameters. Their mechanical rigidity and styli have a firm reputation for
reliable and repeatable surface finish measurements across a wide range of
applications.
The SR Surface Roughness Tester comes in two variants: the SR300 is our
standard offering, while the SR400 offers extended measurement range and
analysis capability.
The SR300 and 400 are battery powered and offers total portability with a
built-in memory capacity (holds up to 100 readings). The instrument can be
used either freestanding (on horizontal, vertical or even inverted surfaces) or
with bench mounted fixtures for batch measurement and laboratory
applications.
