• CT Series’ probes have an extremely low mass
(about 3 grams).
→ there is far less wear and tear on the probe measuring
→ there is far less chance of damage to sensitive coatings
• Contact pressure of the probe remains almost constant whether measurements are taken from above to down, from the side, or above a user’s head.

→ It is possible to take precise measurements on ductile coatings.
•The operation of the CT series is as easy as the one of a mobile phone.
• With protection class IP52, gauges are safe from dust and dripping water.
• FN version automatically recognizes the status of substrate (whether it is ferrous or non-ferrous) and measures correctly due to its dual-functioning sensors.
• No calibration necessary unless required
• Three language option: English, French, German (Other languages on request)

• CT-F, N, FN
- Equipped with an ergonomically designed cabled probe,
it is very convenient and useful to take measurements on small parts and in hard-to-get-at places.

- Clearly smaller and have no cable. Can be asily carried in the breast pocket of a shirt or in the jacket pocket.

Magnetic Induction Method

Method of measuring all non-ferrous coatings such as varnish, paint, enamel, chrome, copper, zinc, etc on steel and iron

Eddy-Current Method

Method of measuring all electrically insulating coatings, such as varnish, paint, anodizing coatings on non-ferrous metals and also on stainless steel


- In the automobile and automobile parts industry
- In paint shops and for electroplaters
- For wet and powder coating operations
- For incoming material inspection during production and for final inspection procedures
- In development engineering and for expert assessment
- In laboratory and field operations
