In order to measure at least one parameter of a mixture of carrier substance, water and gas, the permittivity value of the mixture is measured at different frequencies by means of a network analyzer ( 1 ) and a sensor. The measurements are entered into a mixing formula for forming a system of equations. From the system of equations, at least one parameter of the mixture can be determined. The method is also suited for the measurement of the location dependence of a parameter, e.g. for the measurement of the humidity distribution in concrete.
