M502.300 Roughness Tester — portable, high-resolution surface measurement (Metav IndustryLine)

The M502.300 is a compact surface roughness tester for laboratory and workshop inspections, designed to deliver reliable profilometry across a wide range of roughness parameters with a complete accessory kit.

• High-resolution measurement down to 0.005 µm range
• Rechargeable lithium battery, approx. 20 h runtime
• USB data output and 100-group internal memory
• Supplied with probe, support and protective case
• Conforms to ISO, DIN, ANSI and JIS standards

Precision where it matters: measurable parameters and standards

The instrument offers a broad measurement range for key roughness metrics, covering Ra and Rq from 0.005–16 µm and a wider span for Rz/R3z/Ry up to 160 µm, enabling both fine and coarse surface assessments. Compliance with ISO, DIN, ANSI and JIS standards ensures results are comparable across laboratory and production environments. The specified reading increments for different ranges (e.g. ±20 µm: 0.01 µm) provide a clear expectation of resolution and support confident decision‑making in quality control and process validation.

Dependable data management and sustained operation

Data capture is simplified by the USB interface and an internal memory able to store 100 data groups, allowing batch transfer and documentation without interruption. The integral rechargeable battery delivers roughly 20 hours of operation, minimising downtime during shift work and site inspections. The LCD with 128×64 resolution displays measurements and settings clearly, while compact storage and data export streamline traceability for audits and production records.

Robust probe design and controlled measurement mechanics

A diamond stylus with a 5 µm radius and a 90° tip angle, combined with an application force under 4 mN, provides reproducible contact without damaging sensitive surfaces. Mechanical travel is governed by a Z‑axis range of 160 µm and an X‑axis travel of 17.5 mm, sufficient for standard evaluation lengths; selectable measurement lengths (lr = 0.25, 0.8 or 2.5 mm) and matched traverse speeds ensure conformity with common profilometry protocols. Built‑in filters (RC, PC‑RC, Gauss, ISO13565) allow the operator to apply the correct spectral treatment for feature separation and comparative analysis.

Ready for the workshop and field inspections

The kit includes the measurement probe, an adjustable support, a reference comparison plate, a sensor protective box, charger and cable, and a transport case for secure handling and storage. Rated for operation between −10 °C and 50 °C and 30–80% relative humidity, the unit is suitable for both controlled lab use and typical shopfloor conditions. At approximately 2 kg, the instrument balances portability with stability for repeatable measurements across production lots.

FAQ

What measurement parameters can this instrument record?
The M502.300 records standard surface parameters including Ra, Rq, Rz, Rt, Rp, Rv, R3z, Rsk, Rku and Rsm as well as derived values, enabling comprehensive surface characterisation for most industrial tasks.

How is measurement data exported from the device?
Data is exported via the USB interface; the unit stores up to 100 data groups internally for later transfer to inspection software or a PC for documentation and analysis.

Is the probe suitable for delicate surfaces?
The probe uses a diamond stylus with a 5 µm radius and a 90° tip, combined with a low contact force (<4 mN), which is appropriate for sensitive surfaces while maintaining repeatable tracing.

Which filters are available and why are they important?
Filters provided include RC, PC‑RC, Gauss and ISO13565; these are used to separate roughness from waviness and form, ensuring that the chosen metric reflects the intended surface feature for accurate comparison and process control.

Can this tester be used on the shopfloor under varying conditions?
Yes; the instrument is specified for operation between −10 °C and 50 °C and 30–80% relative humidity, making it compatible with typical workshop environments while ensuring stable measurement performance.
