About Mahr Federal EGH-1026 Surface Analyzer General
The Mahr EGH-1026 general-purpose surface probe is intended for use with the Mahr Pocket Surf series portable surface roughness gauge (sold separately) for most surface analyzing applications. The probe's 90-degree conical diamond stylus has a 5μm (0.0002") radius, which is suitable for use when measuring less-rough surfaces than the 10 micrometer stylus. It measures average roughness (Ra), mean depth (Rz), and maximum depth (Rmax) parameters, and meets International Organization for Standardization (ISO) 4287 and American Society of Mechanical Engineers (ASME) B46.1 specifications. This general surface probe is suitable for applications such as evaluating a machined surface. A surface roughness tester, also known as a profilometer, surtest, roughness gage, surface finish gage, or surf roughness tester, is a device used to inspect and measure surface roughness of flats, rounds, sloping planes, and recesses in machined, ground, or polished metal and non-metal surfaces. It is used for metrology in shop, metalworking, manufacturing, and quality control (QC) applications. Surface roughness testing is a type of form measurement that identifies surface profiles such as grooves and recessions, commonly known as peaks and valleys, of a surface. A roughness tester traces a surface profile using a skid-type (contact-type) method with a tracer tip such as a diamond stylus and piezo-electric detection to calculate roughness. Common types of parameters include Ra (roughness average), Rv (maximum profile valley depth), and Rsk (skewness), and assessed profiles. Profiles can have valuations such as cutoff, sampling, traversing, and evaluation-types of lengths. A surface roughness tester can have analog or digital display. A surface roughness tester can be portable, handheld, or desktop-type. Mahr Federal manufactures dimensional metrology instruments and metering systems. The company, founded in 1861, is headquartered in Goettingen, Germany.
