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
