METRAVI CTG-03 Coating Thickness Gauge User Manual
GENERAL INFORMATION
- This coating thickness gauge works both on magnetic as well as non-magnetic surfaces.
- Uses induction principle or on the eddy current principle, depending on the type of probe used.
- You can select the type of probe manually via MENU system, else it works automatically.

Application
- Designed for non-destructive, fast and precise coating thickness measurement, the principal applications lie in the field of corrosion protection and prevention.
- Ideal for manufacturers and their customers, for offices and specialist advisers, for paint shops and electroplaters, for the chemical, automobile, shipbuilding and aircraft industries, and for light and heavy engineering.
- Suitable for laboratory, workshop and outdoor use.
- Works on both principles, magnetic induction and eddy current.
- Single probe required for coating measurements, for both ferrous and non ferrous metal substrates.
- Adaptable to specific tasks: i.e. can be used on special geometries or on materials with special properties.
Accessories
Gauge/Meter with two AA 1.5V batteries, plastic carrying case, operating manual, steel and aluminum substrates, USB connecting cable, connect software.
Probe
- The probe system is spring-mounted in the probe sleeve, ensuring safe and stable positioning of the probe and constant contact pressure.
- A v-groove in the sleeve of the probe facilitates reliable readings on small cylindrical parts too.
- The hemispherical tip of the probe is made of hard and durable material. Hold the probe by the spring-mounted sleeve and press on object to be measured.
