Precise roughness gauges for consistent surface quality
Roughness gauges are high-precision metrology tools used to measure surface texture and ensure component performance, wear resistance and longevity in industries such as automotive, medical and general engineering. These instruments perform tactile profilometry with a diamond-tipped stylus that records vertical deviations, enabling norm-compliant calculation of parameters like Ra, Rz and Rt to support process control and quality assurance. Available as compact portable units for direct on-machine checks and as stationary bench systems for laboratory analysis, the devices offer high-resolution displays, data storage and modern interfaces for seamless integration with quality management systems. By providing rapid, standardised surface characterisation, these gauges reduce scrap, detect machining errors early and enhance production reliability.

0.5–15 Ra/Rq; 0.1–50 Rz/Rt Compact Surface Roughness Tester Internal Memory, Large LCD, Diamond Stylus 90° - Metav IndustryLine
Take advantage of the combination of compact portability, a diamond stylus for repeatable contact, and an internal memory for up to 500 values to keep production checks efficient and traceable; order the instrument directly via Metav Werkzeuge or ask our consultants if needed. Metav IndustryLine Compact Surface Roughness Tester M502.301 — compact handheld tester with diamond stylus and onboard memory The Metav IndustryLine Compact Surface Roughness Tester M502.301 is a handheld roughness gauge designed for rapid surface checks and machine‑side quality control in metalworking and precision finishing environments. Diamond stylus, radius 0.01 mm, 90° Internal memory for 500 values Large LCD for clear readings Low measuring force <0.016 N Consistent, traceable readings with sub‑micron display clarity The design focuses on reliable numerical assessment: a high‑resolution display (reading step 0.00001 mm) and a repeatable contact tip ensure that profile values are comparable from test to test. With a diamond stylus of radius 0.01 mm and a tip angle of 90°, the probe traces surface contours with minimal wear and stable geometry. The low measuring force (<0.016 N) reduces the risk of local deformation on soft finishes, which supports more accurate characterisation of roughness parameters such as Ra and Rq. Stated variation of ±10% reflects application conditions and sample preparation rather than sensor instability, so routine measurement procedures and consistent probe seating are recommended for best results. Onboard data handling and clear readouts for efficient inspection Data capture is practical: an internal memory for up to 500 values stores individual runs, enabling immediate spot checks without external equipment. The large LCD digital display shows measured parameters clearly and shortens inspection time on the shop floor. The tester runs from a single 1x AA battery, keeping logistics simple and supporting mobile use. Stored values are ideal for transferring by transcription or manual logging into quality records when external data interfaces are not required. Compact mechanics built for workshop use With a lightweight construction of 0.3 kg and compact housing dimensions of 73 x 28 x 62 mm, the instrument is easy to manoeuvre across components and fixtures. The small footprint suits tight measuring positions and frequent relocation between workstations, while the diamond stylus and robust probe assembly tolerate routine handling. This combination of portability and hardened contact geometry makes the tester a practical companion for incoming inspection, in‑process checks and final acceptance tests where access and agility matter. Relevant parameters and typical applications The unit measures standard roughness parameters including Ra, Rq, Rz and Rt, making it suited to finishing checks after turning, milling, grinding or honing. Its characteristics support surface verification on machined metal parts, tooling surfaces and small components where quick numerical confirmation of texture is required. By emphasising robust tip geometry and low measuring force, the tester helps maintain process control without damaging delicate coatings or thin superficial layers.

Ensure process reliability with precision surface roughness testers
A surface roughness tester — also referred to as a roughness tester or stylus profilometer — provides fast, norm‑compliant insight into the surface condition of components. Designed for use in production and the metrology lab alike, these instruments convert tactile measurements into comparable quality data that directly support process control and failure prevention.
How the measuring method secures component function
Most devices operate by the tactile stylus method: a diamond‑tipped stylus runs over the workpiece at constant speed while vertical displacements are recorded and converted according to ISO and DIN standards. The result is a precise display of the primary profile and the material ratio curve, enabling immediate assessment of wear behaviour, friction properties and sealing function in sectors such as automotive, medical technology and general machinery engineering.
Clear benefits that reduce rework and downtime

FAQ
How does a surface roughness tester measure surface quality?
A surface roughness tester measures vertical deviations by moving a diamond‑tipped stylus across the surface at constant speed; the recorded profile is processed according to ISO and DIN standards to produce parameters such as Ra and Rz.
Which roughness parameters can I expect from a roughness tester?
Most roughness testers calculate a range of standardised values, including Ra, Rz, Rq and Rt, simultaneously to provide a comprehensive view of surface condition.
Can these instruments be used directly at the machine or only in the lab?
Both options are available: mobile hand units allow on‑machine inspections, while stationary measuring stations provide higher‑level laboratory analysis and repeatability for demanding inspection tasks.
Are there probe options for measuring in bores and on gear flanks?
Yes. Roughness testers feature replaceable probe modules and specialised free styluses that permit reliable measurements in bores, on tooth flanks and in deep grooves.
