The present disclosure refers to a sensor assembly for an IVD analyzer, the sensor comprising two opposite substrates with at least one fluidic conduit for receiving a sample. The electrodes of different types of electrochemical sensors are arranged on the two opposite substrates facing the at least one fluidic conduit for coming in contact with the sample and determining sample parameters, wherein the counter electrodes and the reference electrodes are formed on one substrate and the working electrodes are formed on the opposite substrate. This achieves optimal sensor-working conditions in terms of a homogeneous and symmetrical electric field density and enables a sensor assembly with simpler geometry and smaller size.
