• QNix® 4200 is for measurements over steel or iron (Fe substrates).
• QNix® 4500 is for measurements over steel AND aluminum (Fe and non-ferrous substrates). This is a best seller for all painting applications.

Whether you are assessing the paint work on an automobile, inspecting an outdoor structure such as a bridge or water tank, or assessing the results from a liquid or powder coating line, these handy and rugged gauges will meet your coating thickness measurement requirements.

The best-selling QNix® 4500 was developed for paint thickness measurement in the automotive industry and other industries with demanding painting applications. This compact gauge permits extremely precise measurements of lacquer and corrosion protection thicknesses, both on steel and iron, as well as on non-ferrous metals such as aluminum, zinc, copper.

• Extremely precise: High measuring accuracy over the entire measuring range.
• Simple operation: No calibration. Only one button. One-hand operation.
• Innovative technology: Proven Hall sensor and Eddy Current technology. Integrated measuring probe without cables or plugs.
• Broad spectrum of use: Dual probe for measurements on steel and non-ferrous metals.
• Protective measuring: Polished ruby tip to protect both probe and surface to be measured.
