Dual-Function Thickness Gauge

The dual-purpose thickness gauge measures the thickness of ferrous and non-ferrous materials based on magnetic induction and eddy current principles, respectively. When the probe contacts the sample, it generates changes in the electromagnetic field, and the instrument converts the signal into a thickness value. It is used for thickness detection of paint coatings, electroplated layers, plastic films, etc., ensuring products meet specification requirements.
Selection
Select magnetic induction or eddy current function based on the type of substrate material; the measurement range should cover the thickness of the object to be measured; consider probe size to accommodate different shapes; pay attention to accuracy values and calibration methods; evaluate the portability and environmental adaptability of the instrument; confirm that the data output function meets recording requirements.
