Abstract
The quantitative determination of two contaminants of a fluid is carried out in the following steps: detection of permittivity ε and viscosity v of the fluid; determination of the quantity of the first contaminanton the basis of a difference between detected permittivity Δε and a first preset value; estimation of viscosityon the basis of the quantity of the first contaminant; and determination of the quantity of the second contaminant on the basis of a difference between detected viscosity v and estimated viscosity
