Measurement parameters & details
Here you can find all relevant information at a glance: technical specifications, performance figures, dimensions, and other important data. This way, you stay informed, can make comparisons, and make decisions based on solid information – clearly, transparently, and reliably.
The QNix® 4000 series coating thickness gauges deliver fast and precise measurement results, are easy to operate, and extremely robust at the same time.
Looking for a universal and proven measuring device that doesn’t require data storage or software-assisted evaluation? Then the QNix® 4200 for measurements on steel and iron (Fe) or the QNix® 4500 for measurements on Fe and non-ferrous metals (NFe) such as aluminum, zinc, copper, or brass is the ideal choice.
Reliable results worldwide
Thousands of users have been successfully using the 4000 series for years. You too can benefit from these proven success models:
- QNix® 4200 – Reliable on steel and iron (Fe)
- QNix® 4500 – Measurements on Fe and NFe
Wide range of applications & easy-to-use
The devices are available in various versions, e.g., with an integrated or cable probe, or with an extended measurement range up to 5 mm. This allows you to cover a wide range of applications.
Following QNix®’s easy-to-use principle: place → measure → read – professional measurement can be this simple.
