Unilateral Thickness Gauge

The unilateral thickness gauge uses a sensor to contact one side of the material, measuring the thickness of coatings or films on the substrate through magnetic induction or eddy current principles. It is used to detect the thickness of paint and electroplated layers, ensuring uniform coating application. Suitable for quality control of metal and plastic substrates.
Selection
When selecting a single-sided thickness gauge, consider the substrate material: use magnetic induction for magnetic substrates and eddy current for non-magnetic ones. The measurement range should cover the sample thickness, with accuracy meeting process requirements. The probe size should match the measured area, and calibration sheets must be consistent with the substrate material. Environmental temperature affects device stability.
