The SRG-4500 is the latest addition to our growing line of precision surface roughness testers and profilometers. This surface roughness tester is "state of the art" with a full slate of advanced features along with precision and accuracy that you demand.

Extremely sensitive and highly accurate readings from the SRG-4500 Phase II surface roughness tester are offered via 15 popular surface roughness scales including Ra, Rq(Rms), Rt, Rz and Rmax.

The SRG-4500 surface roughness tester utilizes an easy interface to allow for changes of in/mm (uin/um), cutoff length, sampling length, parameters, level of test(stylus position), digital filters and more!

Memory, output, battery powered portability are all part of this latest "state of the art" design.

SURFACE ROUGHNESS
MEASUREMENT GUIDE

Surface roughness, for purposes of this forum, is the result of some machining process and its effect on the material surface in question.

Skid type surface roughness testers are common instruments used on the shop floor. A diamond stylus is traversed across the specimen and a piezoelectric pickup records all vertical movement. Peaks and valleys are recorded and converted into a known value of a given parameter.

Parameters differ in how they approach looking at peaks and valleys. The most popular parameter is “Ra”. Ra is commonly defined as the arithmetic average roughness. While the Ra parameter is easy and efficient, there are other parameters that can be more specific and useful depending on the application requirements. It is the parameters that enable us to define surface roughness.

Today, for the purpose of checking Ra values, the use of portable, hand held, surface roughness testers are not only economical, but are digital and easy to use. These surface roughness testers are a given necessity for any shop floor that receives work with Ra requirements.
