摘要： A method and an apparatus for measuring properties of a paper web, whereby at least one property of the paper web is measured at least at two locations in the cross direction of the paper web simultaneously. Adjacent measuring devices are calibrated by traversing a reference sample in the cross direction such that the reference sample is impinged by the measuring beam from each of the measuring devices.

摘要： An arrangement for measuring properties of a moving paper web. The arrangement comprises measuring means for measuring paper properties, in connection with which a plane-like support surface is arranged. The plane-like support surface supports the paper web and extends substantially over the whole width of the paper web in the cross-direction relative to the direction of travel of the paper web. An opening arrangement formed by at least one opening is arranged on the support surface for measuring properties of the paper web.
