Anodic Sealing Quality Tester

Listing ID #1475114

Anotest® ymp30-s sealing quality tester for anodic coatings on aluminum:-
the weather resistance of a finish is a function of sealing quality. According to din en iso 12373-5 and astm b 457-67, the admittance (y) of a capacitor in which the anodic oxide film forms the dielectric is a good yard-stick of sealing quality.
Measurement procedure:-
a self-adhesive rubber ring is placed on the surface to be tested and the space so enclosed filled with a few drops of a test fluid. The aluminum substrate is then connected to the earthing socket of the unit and the test electrode dipped into the cell fluid, thereby forming a capacitor in which the anodic film acts as the dielectric. It is the admittance of this capacitor which is measured and directly indicated in μs (micro siemens).
