Glass corona pen

The glass corona pen generates plasma on the glass surface through high-voltage discharge, altering its surface energy to facilitate liquid spreading. It is used to assess the effectiveness of glass surface treatments, evaluate cleanliness or coating adhesion, and is commonly employed for surface quality inspection prior to printing or coating applications.
Selection
When selecting, consider that the nib material needs to be wear-resistant, the output voltage should match the material being tested, and there should be a clear battery level indicator. Refer to the test values of standard liquids based on common substrate types to ensure operational safety and facilitate quick on-site testing.
