Calotest

The calotest allows to measure the thickness of hard coatings quickly with the greatest precision.
Two instruments on one : the only calotest instrument 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.

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

Measured value : thickness
Technology : electro-optical
Applications : industrial, laboratory
Configuration : benchtop
