Instrument for measuring thickness of thin hard coatings, rapidly.
Two instruments on one : the only calotester on the market which suits both for laboratory samples
and big industrial parts.

In accord with Standard : ISO EN-1071-2 and VDI 3198


Manufacturers and users of hard coatings are often confronted with the problem of the measurement of the thickness of coatings. TRIBOtechnic has created a new and innovative instrument called CALOTESTER fully equipped with all items needed for measuring thickness of coatings, at your finger tips: programmed spherical abrasion controlled by microprocessor; microscope for measurement of abraded coatings and a calculator to supply the results of thickness automatically.


 calotester - Tribotechnic

Procedure :

A ball coated with an abrasive paste is kept in rotation on a specimen by shaft with a groove.
A form of a spherical cap is abraded into the specimen,
X and Y are measured with an optical microscope.


The thickness E of the coating will be calculated with the following equation:

Applications :

The method is applicable in the following fields:
- PVD and CVD coatings
- Sputtering, ion plating
- Evaporation in vacuum
- Anodic oxidation
- Galvanized coatings
- Chemical coatings
