Features of eddy current thickness gauge
1. The dual-function built-in probe is used to automatically identify iron-based or non-ferrous matrix materials, and select the corresponding measurement method for accurate measurement.
2. Ergonomically designed dual-display structure can read measurement data at any measurement position.
3. The mobile phone menu-style function selection method is adopted, and the operation is very simple.
4. The upper and lower limit values can be set. When the measurement result exceeds or meets the upper and lower limit values, the instrument will emit a corresponding sound or flashing light to prompt.
5. The stability is extremely high, and it can be used for a long time without calibration.
The measurement methods of coating thickness mainly include: wedge cutting method, optical section method, electrolysis method, thickness difference measurement method, weighing method, X-ray fluorescence method, β-ray backscattering method, capacitance method, magnetic measurement method and eddy current measurement law etc. Among these methods, the first five are destructive testing, the measurement methods are cumbersome and slow, and most of them are suitable for sampling inspection.
