Abstract

The present invention relates to a dialysis machine that is configured to be equipped with an extracorporeal blood system comprising a dialysis solution system that is configured to be equipped with a dialyzer, wherein a mixing region, in particular a mixing chamber, is provided in which the fresh dialysis solution or a component thereof is located in the operation of the dialysis machine, with a concentrate line being in fluid communication with the mixing region, through which concentrate line concentrate can be conducted from a concentrate container into the mixing region, wherein at least two electrically conductive elements are arranged spaced apart from one another in or at the concentrate line or lines; that a measuring device is provided which is electrically connected to the conductive elements and which is configured to measure the conductance or a value correlated therewith between them; and that a control unit is provided which is configured to compare the measured value with a desired value, with a limit value, or with a desired value range.
