Method of operating a measuring device for determining the particle content of a medium by the filter principle and apparatus for performing the method

摘要

To reduce the consumption of filter material in the determination of the particle content of a medium by the filter principle, after the particles have been accumulated and subsequently measured, the filter material is freed of the sample residues in a regeneration unit and supplied for reuse in further sample collection. To simplify handling, the filter material may, for example, be a tape-type strip contained in a cassette unit. Furthermore, the cassette unit may contain the regeneration unit, which contains a chemical and/or ultrasonic cleaning bath. <IMAGE>
