SR300 and SR400 Surface Roughness Tester
SR300 AND SR400 OVERVIEW

SR300 and SR400 Surface Roughness Tester
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.

INSTRUMENT OVERVIEW

SR300 and SR400 Surface Roughness Tester
Instrument Overview
Parameter Options to Suit Your Application The SR300/SR400 can calculate up to 22 parameters
according to your measurement application including:
Amplitude Parameters
Measures the vertical characteristics
of the surface deviations:
•Ra (Arithmetic Mean Deviation)
•Rsk (Skewness)
•Rz (Average peak to valley
height)
•Rt (Total height of profile)
•Rp (Max profile peak height)
•Rz1max (Max peak to valley
height)
Spacing Parameters
Measures the horizontal
characteristics of the surface
deviations:
•RPc (Peak count)
•RSm (Mean width of profile
elements)
Hybrid Parameters
Combinations of spacing and
amplitude parameters:
•Rmr (Material Ratio)
•Rda - R Delta a (Arithmetic
Mean Slope)
The above parameters cover the most common requirements to check
lubrication, feed rates, stresses, friction and wear properties.
Additional parameters can be analysed with the addition of Talyprofile software.

Instrument Overview
Intuitive Menu Structure
The SR300/SR400 incorporates a large LCD screen which allows full
menu and measurement results to be displayed. Using only two buttons
the user can scroll through the menus and make selections intuitively
before pressing the MEASURE key. All selections are saved for future
measurements. All the measurement criteria and results are displayed
clearly on the screen ready to print or export to a PC.
Fast Measurement Cycle
The SR300/SR400 incorporates the
latest electronics for very fast analysis -
results are calculated and displayed
even before the traverse unit returns.
This fast processing, combined with
intuitive menu buttons, greatly reduces
measurement cycles.
Powerful Software Options
The SR300/SR400 includes Type A
USB and USB mini ports which allow
connection to a printer or exportation of
results to a PC for further analysis using
the optional Talyprofile software. By
setting the SR300/SR400 to 'Data
Dump' mode, measurements can be
instigated directly from the Talyprofile
software.

SR300 and SR400 Surface Roughness Tester
Instrument Overview
Unique Stylus Lift Mechanism
The SR300/SR400 has a uniquely engineered stylus lift
mechanism which allows a vertical adjustment of 50mm and
rotation of the pick-up to different measuring positions, including
right angle or inverted measurements. These adjustments to the
height and position of the gauge allow areas and features of a
part to be easily measured without additional fixtures. This
feature saves the operator a huge amount of set up time and
allows total flexibility. Typical applications where the stylus lift is
invaluable include the measurement of steps, bores, grooves and
lands.
Built-in Memory/Storage
No PC or printer cables in your way while you
measure –the SR300/SR400 is now truly
portable: Take your surface roughness tester
wherever you need to take measurements,
save as many batch readings as you need
(max 100 measurements) then download to
your PC or printer at your convenience.
External Memory
Storage is expandable with a standard
USB stick. The 4 GB USB stick provided
with the unit is capable of storing over
64,000 screen shots and/or
measurements

SR300 and SR400 Surface Roughness Tester
Instrument Overview
Long Traverse Length and Extended
Pick-Up Reach
The SR300/SR400 can traverse up to 25mm (or as little
as 0.25mm) depending on your component. In addition,
the stylus length and pick-up configuration give a long
reach, making it an ideal instrument for features such
as large and narrow bores. Optional extension rods
extend the pick-up further.
Comprehensive Range of Accessories
and Pick-Ups
Starrett has developed an extensive range of pick-ups
and accessories to suit the varied measurement needs
of our customers. In addition to the pick-ups shown on
page 6 our applications department regularly designs
and manufactures pick-ups and fixtures for specific
requirements.
