GalvanoTest: Coulometric coating thickness measurement

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.

Measuring range between 50 nm and 75 µm

Measuring surface ranging between 0.25 and 8 mm²

Optimal measurement concept.

Predefined measurement tasks for different coating systems

Intuitive operation.

Color display and graphically supported user guidance

Individually expandable.

Extensive accessories enable practical work and safe storage

Maximum flexibility.

Exact coating thickness measurement of almost any coating-substrate-combination

Measuring method:

Coulometry by anodic stripping

Measured value memory:

3,000 in 50 applications

Measuring Range :

Depending on the coating-base material combination and the removal speed 0.02 - 50 µm

Inbuilt Feature :

Almost 100 predefined measuring tasks for different coating systems (such as zinc on iron or nickel on brass)

Speed Selection :

Simple selection of the detachment speed (0.1 - 50 µm/min) and the detachment area (0.6 - 3.2 mm Ø)

Measuring method: Coulometry by anodic stripping

Applied Standard :

Functions for STEP test measurement in accordance with ASTM B764 - 04 and DIN EN 16866

Data Transfer mode :

Simple data transfer via USB interface

The GalvanoTest coating thickness measurement gauge is available in two variants:

• 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.

Ideally suited to measuring coating thickness in virtually any single or multi-layered coatings such as chrome, nickel, cadmium, copper, brass, silver, gold, tin or zinc both on metals and non-metals.
