The Robust coating thickness measurement gauge Minitest 650FN

The MiniTest 650 is used for measuring non-magnetic coatings on steel and insulating coatings on nonferrous metals. It features a fixed external probe that is suitable for all non-magnetic coatings on steel and insulating coatings on nonferrous metals. This gauge is commonly used in industries such as manufacturing, automotive, and construction.

The MiniTest 650 FN, on the other hand, is specifically designed for measuring non-magnetic coatings, such as varnishes and enamels, on ferromagnetic substrates like steel used in construction and auto body applications. It can also measure insulating coatings, such as anodic coatings, on non-ferrous metals like aluminum, copper, and brass.

Both gauges have a measuring range of 0 to 2 mm and allow for interchangeable measuring units in micrometers (µm) or mils. They also offer 1-point and 2-point calibrations, which enable you to calibrate the gauge using known coating thickness standards to ensure accurate measurements.

Additionally, these gauges provide a statistics display that shows the number of readings taken, mean values, standard deviation, maximum, and minimum values. This feature allows you to analyse and evaluate the coating thickness measurements for quality control purposes. MiniTest 650 and MiniTest 650 FN are reliable and versatile coating thickness measurement gauges suitable for various coating applications on different types of substrates.

The MiniTest 650 and MiniTest 650 FN are non-destructive coating thickness measurement gauges that employ different measuring principles based on the type of coating and substrate being measured.

For non-magnetic coatings on ferromagnetic base materials (e.g., steel), the gauges use the magnetic induction method (F-type sensors) according to DIN EN ISO 2808, method 7C. This method measures the coating thickness by generating a magnetic field and analyzing the changes in the field caused by the presence of the coating.

For insulating coatings on non-ferrous metals (e.g., aluminum, copper, die-cast zinc), the gauges use the eddy current method (N-type sensors) according to DIN EN ISO 2808, method 7D. This method measures the coating thickness by inducing eddy currents in the conductive substrate and analyzing the changes in the currents caused by the coating.

Both gauges offer a measuring range of up to 2 mm (MiniTest 650) or 3 mm (MiniTest 650 FN) for accurate measurement of various coating thicknesses.

The gauges feature a universal probe that can automatically identify the substrate, allowing for quick measurements on both steel and non-ferrous metals without the need for manual adjustments.

The probe tips of the gauges are wear-resistant and designed for long-lasting durability, ensuring reliable performance over time.

The gauges are equipped with a USB interface, enabling you to transfer measurement data to a PC for further analysis and documentation.

Furthermore, the gauges provide statistical evaluation of the readings, allowing you to analyze the measurement data by displaying mean values, standard deviation, maximum, minimum, and the number of readings taken. This feature facilitates quality control and data analysis for coating thickness measurements.

In summary, the MiniTest 650 and MiniTest 650 FN offer non-destructive coating thickness measurement capabilities using magnetic induction and eddy current methods, respectively. They provide features such as a wide measuring range, automatic substrate identification, durable probe tips, data transfer to a PC, and statistical evaluation of measurement data for enhanced usability and analysis.
