German EPK Coating Tester MiniTest600B Information

The operation of Minitest 600b is very simple, requiring only a small amount of training or no training to easily control. Calibration is easy, and the measurement results on the large display screen are intuitive, with stable and accurate readings, which is well received by users. The N-type probe uses eddy current method to measure the thickness of non-conductive coatings on non-magnetic metal substrates (such as copper, aluminum, zinc, tin, etc.) and austenitic stainless steel (such as rubber, paint, plastic, anodized film, etc.).

German EPK Coating Tester MiniTest600B Information and Data Characteristics:

■ Compact and suitable, fast measurement
The top of the probe is made of highly wear-resistant hard material
F-type probe is used for non-magnetic coating on steel, such as paint, plastic, enamel, chromium, zinc, etc
N-type probes are used for all insulation layers on non-ferrous metals (such as copper, aluminum, austenitic stainless steel), such as anodized films, paints, coatings, etc
The FN probe is a dual-purpose probe developed to automatically switch measurements on magnetic and non-magnetic substrates

Precautions for calibration of coating thickness gauge:
Attention should be paid to the following points when calibrating coating thickness gauges:
Correct calibration is crucial for measurement. Regarding calibration, a sample similar to the object being measured later will be used, that is, both the standard specimen and the object being weighed should have the same shape and geometry. Fundamentally, more standardized sample matching for measuring objects will lead to increasingly higher measurement results.
2. Confirm that the calibration sample matches the following properties of the measured object: - curvature radius of the surface - substrate data (such as magnetic permeability and conductivity; ideally, the standard sample and measured object should have the same data) - substrate thickness - size of the measured area
Before starting the calibration, ensure that the calibration points, sensor prompts, and calibration examples are clean. If necessary, remove any deposits such as grease, metal shavings, etc. Any impurities may affect calibration and cause instability in calibration.
4. Ensure to always find their respective calibration positions, especially for measuring small parts and corners. The small parts initiative utilizes measuring brackets.
5. Stay away from strong magnetic fields during the calibration process.
6. More calibration specifications that can match the expected thickness will make calibration and measurement more accurate.
7. According to the electromagnetic induction method, measure the thickness of non-ferrous metal coatings on steel or iron substrates and require multi-point calibration. The thickness specification sample must be made of the same metal as the object to be measured in the future.
If calibration foils are used, ensure that they are placed on the flat position of the substrate data. The air gap under the foil must be prevented as this will result in unstable readings. If it is curved aluminum foil, make sure they are placed on the substrate as shown below.
9. Fine thickness specifications must be handled with care. Any wear and damage to the thickness specifications will be reflected as incorrect calibration values. Do not fold the calibration foil. Any bending will result in air gaps under the film, leading to unstable readings. Adhere to the cleanliness of thickness specifications. Any grease, oil, dust or other accumulation must be prevented. The accumulation of aluminum foil will be considered as thickness and will result in measurement errors equal to the thickness of the accumulation. Let me give you a rough idea: a pile of fingerprints is enough to form an additional thickness error of several micrometers.
