摘要

The arrangement has a measurement unit (10) providing an output signal based on particle concentration of gas in measuring volumes (11a, 11b). A dilution unit (12) adjusts the particle concentration in the measuring volumes by two different dilution factors. A signal processing unit (14) determines a correction factor for the output signal of the measurement unit, where the output signal contains the dilution factors. The measurement unit comprises an electrical measurement unit for determination of the particle concentration of the gas. An independent claim is also included for a method for determining concentration of particles in gas of a combustion engine.
