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

Instrument Overview

SR300 and SR400 Surface Roughness Tester

	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

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

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.

Instrument Overview

SR300 and SR400 Surface Roughness Tester

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

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.

SR300 and SR400 Surface Roughness Tester

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.
