| SURFACE ROUGHNESS TESTERS |
Need a quick, easy and accurate Ra reading? The Phase II SRG-1000 is the surface roughness tester you’re looking for! Pocket sized and economically priced, this surface roughness tester determines both roughness parameters Ra and Rz accurately within a wide measuring range. The piezo-electric pickup stylus with diamond tip assures reliable measurements within tolerances that conform to ISO class 3. Surface roughness parameter Ra is computed to conform to ISO and Rz is computed to DIN.
Easy to use the SRG-1000 surface roughness tester operates on various surfaces, not only flat, but also outer cylinder, outer cone, grooves, and recesses greater than 80x30mm. Readings are achieved with the push of a button. External calibration of the roughness values is possible by means of a calibration button, which makes adjustments simple and quick. Three cutoff lengths are easily selected via the friendly interface. |

Surface Roughness Tester 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. |
