The measuring system determines the alcohol content of an aqueous solution. On one side the conductivity of a gas sensor is measured, on the other side the temperature in the solution. Both of them are combined together through a mathematical formula in such a way, that displays either an alcohol concentration between 0,0 and 7,0 Vol% or between 0,0 and 7,0 Vol‰. This information can be transmitted to the controls of any process superordinate systems (process control, control panels). The microcomputer has a lighted up LC-display and the operating takes place with the help of a membrane keyboard.
