- 2 MarSurf. Surface Measuring Instruments PRODUCTION-RELATED ROUGHNESS MEASURING. MOBILE WITH MARSURF Wherever surface structures influence the function, processing or appearance of components or products, careful testing is essential. But how can surfaces be tested? At the start of the 20th Century, experts still had to test by eye and touch. A practiced eye can detect features in the ìm range, and even the much maligned thumbnail test delivered perfectly acceptable results. Now however, we live in an age of exchangeable parts, fits and internationalization, where subjective tests like this...

4 Pocket Surf. Portable Surface Roughness Gage - Important Definitions and Surface Parameters Real surface separates a body from the surrounding medium. (DIN EN ISO 4287) Stylus instrument enables two-dimensional tracing of a surface. The stylus is traversed normal to the surface at constant speed. (DIN EN ISO 3274) Traced Profile is the enveloping profile of the real surface acquired by means of a stylus instrument. Parameters usually are defined over the sampling length. An average parameter estimate is calculated by taking the arithmetic mean of the parameter etimates from all the individual...

Perthometer M1. The Basic Model for Roughness Measurements Entry-level roughness measurement Features This instrument serves for determining and documenting the most common parameters as per DIN EN ISO/AMSE/prEN 10049 (Ra, Rz, Rmax, and RPc) and according to the JIS Japanese standard (Rz, Ra). With a minimum of keys, the Perthometer M1 is characterized by a multitude of functions. An automatic function enables periodic and aperiodic profiles to be identified and the cutoff to be set according to standards without any prerious test measurement, such that unintentional non-standard measurements...

+ 11 The operation of this instrument is based on the well-proved catalog of functions which enables instrument settings such as measuring conditions, language and record contents to be selected very easily. The Perthometer M2 thus offers a maximum of comfort and flexibility. Compared with the Perthometer M1, this instrument not only meets the requirements for determination and documentation of selected parameters, but also makes most of the parameters and characteristic curves stipulated in DIN/ISO/JIS available for the evaluation of the profile assessed. Moreover, the Perthometer M2 offers...
