Coat Measuring System

Coat Measuring System

The Kr coat measuring system is used for continuous, non-contact measurement of coating layers using the isotope-based backscatter method.

The number of measuring heads required depends on the type of application (wet or dry).

The traversing measuring system measures the individual coat layers (primer & finisher) over the entire strip width.

To this end, the characteristic properties of different types of coating can be stored in a database.
