Features of the CALIX

Easy to use

Fast adjustment and calibration through the diagnostic and parameterization tool specially developed by LAP.


The sensors have no contact with the measured object and leave no traces on the measured surface.

Material independent

The CALIX measures reliable - regardless of metallurgical material properties and surface condition.

The Calix S uses laser technology to measure the thickness of narrow strips and sheets inline and without contact.


The compact measuring frame of the LAP CALIX S is especially suitable for edge measurements on the production line and for small strips. Due to its space-saving design as well as fast calibration, the LAP CALIX S is an ideal complement to all cold strip processing lines.

The Calix XL uses laser technology to measure the thickness of strip steel and sheet metal inline and contactless.


For measurements in the centerline of the material or over the entire material width, the LAP CALIX XL offers the right solution with its traversing thickness measurement.
