Checking tightness without contact
The quality of sealing surfaces has a decisive influence on preventing connections from leaking over time in the long run. To achieve this, the surface’s geometric properties must be defined as precisely as possible so that the intended function — in other words, leak-tightness — is fulfilled. Leaks can occur particularly if the contact surfaces’ form deviation is outside the defined tolerances.
This risk can be prevented by using Polytec’s surface measurement systems. Using these products allows you to characterize tightness not only in the lab, but also during production. Thanks to the contactless measuring method, both the form and consistency of the sealing surfaces to be inspected are maintained and the measurement results can be repeated at any time. The Polytec systems are easy to use and make fast analysis process.

Where surface inspections need to comply with cycle times
Polytec surface measurement systems are “in their element” in all production operations where tight cycle times have to be complied with. This situation is a particularly frequent one in the automotive industry – for example where injection systems, Piezo common rail systems and compressors are used, and for motor development in general.
Fitting optical profilers for sealing surfaces
Micro Profiler
Micro.View profiler systems are optimized for measurements with sub-nanometer resolution. With focused optics and high vertical resolution they enable detailed analysis of microstructures, surface finish and material distribution where even the smallest deviations matter.
Macro Profiler
Pro.Surf inspects flatness, step height and parallelism on large parts and multi-part trays — non-contact, in seconds. No-crash telecentric optics measure even into bores, with the precision and repeatability production demands.
Metro.Lab
Metro.Lab is a compact, wide-area surface profiler. It combines high measurement performance with a small footprint—ideal for space or budget conscious applications that still require reliable 3D surface data.
Not sure which profiler fits your task? Two guides to help you decide.
Two short guides take you through the key decisions: one helps you choose the right measuring technology, the other the right measurement scale — micro or macro. And with our try-before-buy offer, you get the practical way to confirm your choice on your own parts.
