A portable electronic device comprises a chemical sensor that is sensitive to a concentration of a chemical analyte and at least two auxiliary sensors that are sensitive to parameters that are different from the concentration of the chemical analyte. The portable electronic device comprises a control device that receives signals from the chemical sensor and from the auxiliary sensors at a plurality of points in time distributed over a measurement period and correlates the time dependencies of these signals to obtain a corrected reading of the first chemical sensor. The portable electronic device may be employed for breath analysis.
