How to measure Mil Thickness with QNix Digital Paint Thickness Gauges - for non-destructive Dry Film Thickness measurement –

QNix® brand by Automation Dr. Nix - Made in Germany

The quality of your Paint Film Thickness Gauge depends on several factors, among other the streamlined production processes, choice of raw material, resources performance, and expertise. Paint thickness gauges for dry film paint thickness measurement also play an important role in determining the paint quality of coating systems- used during the application and inspection of the coatings in uncured and cured stages. Applying coatings according to paint manufacturer’s specifications and regular thickness measurements reduce the cost of product maintenance and waste of resources. Whether mechanical or electronic coating thickness gauge (also called dry film thickness gauges -DFT, mil Gauge, paint meter or paint thickness meter) non-destructively measure the dry film thickness (DFT) on metal substrates, such as powder coatings, anodizing and electroplating on metal substrates such as steel, iron, aluminum, zinc or copper.

We can't find products matching the selection.

There are two distinct methods to measure Dry Mil Film/coating thickness: The destructive Coating Thickness measurement and the Non-destructive coating thickness measurements.  With the former, the coating is cut through and down to the substrate with a cutter. This technique involves damaging the applied coating, which is considered by many as not being very cost-effective and laborious. Wet film thickness might be considered another type of destructive film thickness measurement method. The method that does not damage the coating of a dry film is the non-destructive method. In this case, coating thickness is measured using different types of coating thickness gauges, determined by the measuring principles of operation. Mechanical Coating Thickness gauges are cost-effective and use the magnetic principle to measure dry film thickness on steel substrates. They are preferred in certain applications due to the robustness and the lack of complicated electronic systems. More advanced Coating thickness gauges use magnetic or hall sensor principles to measure dry film thickness on non-ferromagnetic coatings on ferromagnetic substrates such as steel and iron. They also use the Eddy – current method to measure non-ferromagnetic and electrically non-conductive dry film thickness on non-ferromagnetic and electrically conductive substrates such as aluminum, zinc, brass, and certain (high-grade) stainless steel substrates.

 Without compromising on quality, the Automation Dr. Nix - QNix® brand offers a wide range of dry film Paint thickness Gauges/meters -DFT Gauges for precise and non-destructive measurement of coatings. We draw back from decades of experience in heavy-duty corrosion protection, industrial painting and contract coating, surface finishing with galvanized and anodic coatings as well as vehicle assessment and bodywork to design our gauges. Non-destructive dry film thickness measurements in accordance with ASTM Practice D7091 - A typical QNix Paint Coating Thickness Gauge tolerance is between ± 0.04 mil and 2% of the measurement range 0-80 mils and 3% above 80 mils (new models). This measuring range is ideal for powder coating thickness gauges. Mils means the unit of length in a metric system. Higher measuring ranges up to 200 mils are ideal for fireproofing thickness gauges.

Automation Dr. Nix Paint / Coating thickness gauges for non-destructive measurement – QNix® series. Facts about QNix coating thickness MIl Gauge - DFT Gauges - Paint depth meter QNix® gauges If you have been doing one and the same thing and improving by learning for over 6 decades, you can call yourself an expert. Designing and manufacturing a coating thickness gauge is the core competence of Automation Dr. Nix. A type II (2) or electronic Paint/coating thickness gauge (also called dry film thickness gauges, paint meter, or paint thickness meter) measures the dry film thickness (DFT) on metal substrates non-destructively. QNix Paint thickness Gauges operate on the electromagnetic induction principle, Hall sensor principle, and the Eddy current principle. Derived from these principles, sensors are designed for a variety of industrial applications. The two Fe measuring principles ( Ferrous metal substrates) allow for coating thickness measurement of dry coating, powder coatings, anodizing, and electroplating on metal substrates such as steel, iron, aluminum, zinc or copper. A non-destructive QNix® coating thickness gauge measures the Paint/coating thickness on metal substrates. The substrate must either be magnetic or electrically conductive. The Non-Ferrous dry film thickness measuring principle (Non-ferrous metal substrates) allows for coating thickness measurement of electrically insulated coating thickness on electrically conductive substrates; Automation Dr. Nix offers a broad range of dry film paint thickness gauges for precise and non-destructive measurement in many industries, including automotive manufacturing, automotive aftersales, corrosion protection, powder coating, car body shops, product finishing, meteorology, laboratory, etc, The many years of working with experts in heavy-duty corrosion protection, gas, industrial painting, and contract coating, surface finishing, and bodywork, makes Automation Dr. Nix a reliable partner in these industries. QNix coating thickness gauges are one of the most reliable, easy to use, durable, and are proven to pass the Repeatability & Reproducibility (R & R) test.

Automation Dr. Nix provides a kit with 5 pieces of transparent certified shim sets of different thicknesses. Newly launched QNix 5500 and QNix 9500 come with two non-certified transparent shims.

QNix® Coating thickness Gauges for dry film thickness measurement

by Automation Dr. Nix

A non-destructive QNix® Paint/ Coating thickness Gauges for dry film thickness measurement measures the dry film thickness on metal substrates. The coating thickness base must either be magnetized or electrically conductive for this purpose. Our paint meters/gauges then use the right measurement method. The development of our paint thickness testers/gauges conforms to national and international standards such as DIN EN ISO 2808, DIN EN ISO 2178, DIN EN ISO 2360, DIN 50981, BS 5411 (11). Non-destructive coating thickness measurement on metal substrates can be roughly divided into two measurement methods: Measurement on a ferromagnetic substrate such as iron or steel: The type of substrate and the associated measurement mode usually have the brief designation Fe. The measurement methods utilized here are those that take advantage of magnetic induction. A magnetic field is generated by a permanent magnet or electromagnet and measured with a Hall sensor (electromagnet or permanent magnet possible) or a secondary coil (only electromagnets). Measurement on a non-ferrous or non-ferromagnetic but electrically conductive substrate such as aluminum, zinc, copper, brass, and certain stainless steel types: This type of substrate and the associated measurement mode are designated with Non-ferrous. The eddy current method is utilized.

Automation Dr. Nix offers a wide range of QNix® Coating thickness Gauges for dry film thickness measurement, as well as probes for many fields of application. All conventional measurement methods are used: Magnetic induction with electromagnet and measurement with the secondary coil (magnetic induction measurement method) – DIN EN ISO 2178. Magnetic induction with electromagnet and measurement with Hall sensor – DIN EN ISO 2178. Magnetic induction with permanent magnet and measurement with Hall sensor – DIN EN ISO 2178.
