GalvanoTest Coulometric coating thickness measurement gauge
The anodic dissolution method, also known as the coulometric method, functions similarly to the electroplating process: an electrolyte separates individual metal coatings from the substrate with the help of an electric current. By measuring the current and time, the GalvanoTest determines the thickness of the separated coating.
Ideally suited to measuring coating thickness in virtually any single or multi-layered coatings. The GalvanoTest uses the coulometric method to measure galvanised coatings such as chrome, nickel, cadmium, copper, brass, silver, gold, tin or zinc both on metals and non-metals.
Models Available
GalvanoTest 2000
the electrolyte is circulated by a pulsator nozzle.
GalvanoTest 3000
large electrolyte volumes circulated by a circulation pump enable quick serial measurements. Suitable for use on very small parts and for the measurement of gold layers.
