Pocket Roughness – compact solution with 8" touchscreen, ideal for production environments.
Roughness Tester Retrofit
Multi-brand retrofit
Not a repair: a structural upgrade.
Keep the mechanics that still perform and modernize electronics, interfaces and software for better traceability, quality reports and process standardization.
- An alternative to buying new, with a complete upgrade of control and data management.
- Pocket Roughness (touchscreen) or Surfynex (PC): same measurement logic, better usability.
- Ready for traceability and QA workflows (database, export, reports).
A structured-company approach
- Technical analysis and feasibility
- Electronics + software integration
- Testing and configuration release
- Support and long-term continuity
Continuous technological progress often makes measuring machines obsolete even when the mechanical part is still accurate and fully functional. The limitation typically comes from outdated electronics or software that can no longer be updated and may not comply with the latest standards.
In these cases, a retrofit is an effective and cost-efficient alternative to purchasing a new machine. With our interface kit, you can keep the original mechanical structure and replace only the electronics and software, giving the instrument a second life.
We offer two main retrofit solutions: Pocket Roughness (integrated touchscreen) and Surfynex (advanced PC software for analysis and reporting).
Retrofit kit – modern electronics and updated interfaces while keeping the original mechanics.
Why choose MCM Technic for retrofit
Multi-brand retrofit specialists
We work on instruments from different brands with a unified measurement and reporting workflow.
In-house electronics and software

Long-term service continuity
Support, repairs and overhauls after retrofit: your machine stays serviceable over time.
Retrofit process in 4 steps
1
Analysis & feasibility
Brand, model, accessories and application. We define solution and compatibility.
2
Electronics design
Interfaces, control, optional encoder upgrades and peripheral integration.
3
Software & configuration
Pocket Roughness or Surfynex: parameters, procedures, reports and data handling.
4
Testing & release
Functional testing and delivery of the operational configuration. Post-support included.

When a retrofit makes sense
Accurate mechanics, outdated electronics
The mechanical quality is there: upgrade the “smart” part of the instrument.
Software no longer supported
Compatibility with modern systems and QA workflows (export, database, reports).
Official support no longer available
Retrofit makes the instrument serviceable and maintainable again over time.

New instrument vs Retrofit
| Buying new | MCM Technic retrofit |
|---|---|
| High investment | Lower cost compared to new (depending on model/configuration) |
| Procurement and commissioning lead time | Targeted upgrade keeping mechanics and reducing downtime |
| Full new training | Modern interface and standardized procedures |
| Disposal/relocation of the old instrument | Second life for the instrument with long-term service continuity |
Frequently asked questions
How long does a retrofit take?
It depends on the machine complexity and the instrument condition (for example, if it has already been retrofitted). Typically we complete a retrofit within 4–6 weeks.
Do we need to stop the machine?
It depends on the retrofit: for simple and already-known solutions we don’t always need the instrument. For more complex solutions the machine may need to stop, but to reduce production impact we can provide loan solutions during the retrofit period. This keeps the customer covered and also allows early familiarization with our software.
Can I keep the original probe/stylus?
Yes. We keep the original mechanics and measurement system, integrating it with our electronics and software.
Do you also perform repairs or overhauls?
Yes. If there are damaged parts we can restore or replace them. Since we manage electronics and software, we can also adapt the system to future changes or upgrades.
What if something fails in the future?
We ensure long-term continuity: we provide repairs or replacements of damaged parts, including the probe, to keep the machine operational and up to date.
