SRG-4000 PORTABLE SURFACE ROUGHNESS TESTER / PROFILOMETER
The latest in state-of-the-art surface roughness testers / profilometer, the SRG-4000 is designed with the shop environment in mind. These surface roughness testers / profilometer are distinguished by a high level of accuracy, multiple parameters and simplicity of operation. Extremely sensitive and highly accurate readings from this Phase II surface roughness tester/profilometer are offered via multiple surface roughness profilometer parameters, Ra, Rq(Rms), Rt and Rz.
Features:
- Menu driven operating system
- 4 Different roughness parameters
- Inside/Outside Diameters
- Stylus position indicator
- RS 232 output to printer/PC
- Extended memory functions
“The diamond stylus” is hypersensitive and sophisticated enough to allow for a .001 (um) micron display resolution. The SRG-4000 surface roughness testers/profilometer utilize 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! Measurement results are displayed as large characters on the LCD screen for easy recognition.
Battery powered portability allows the SRG-4000 surface roughness testers/profilometer to mobilize productivity throughout the shop.
Optional accessories available for the SRG-4000 surface roughness testers/profilometer include:
-2um Stylus
-Extension Rod
-Stand
-NIST certified surface roughness standard

Surface Roughness Tester Measurement Profilometer 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/profilometer 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/profilometer are not only economical, but are digital and easy to use. These surface roughness testers/profilometers are a given necessity for any shop floor that receives work with Ra requirements.
The PHASE II SRG-4000 Surface Roughness Tester/Profilometer comes complete with a compact durable carrying case, roughness standard, and instruction manual.
