Surface Roughness Testing

Product Details

Starrett Surface RoughnessTesters

Easy to use and accurate, the new Starrett Surface Roughness
Testers are both accurate and designed for easy measurements.

The innovative SR100 separates into two pieces to measure surface
roughness. The bottom half contains the traverse mechanism which
is designed for stability when placed on the surface to be
measured. The upper half has a large LCD display, as well as
controls and is easily hand-held for easy operation and clear
viewing.

The SR200 is a powerful and versatile surface roughness tester
with batch measurement capability for laboratory applications.
The SR200 can calculate results even before the traverse unit
returns. With up to 10 different parameter measurements, a large
LCD and intuitive operation, the SR200 is a powerful yet easy to
use unit that can be mounted vertically, horizontally or even
bench mounted. The SR200 is also portable thanks to its battery
operation (AC Adapter available) and built-in memory for PC free
operation. The Starrett SR200 is available with a number of
pick-ups to meet a variety of measurement
requirements.*
