A fluid warming device for an extracorporeal blood treatment apparatus, comprises: an outlet temperature sensor () operatively active at an outlet () of a fluid warming path () to detect a measured outlet temperature (To) of a fluid leaving the fluid warming device (); an electronic control unit () operatively connected to the outlet temperature sensor (). The electronic control unit () is configured to perform the following procedure: receiving, from the outlet temperature sensor () a signal correlated to a measured outlet temperature (To); correcting the measured outlet temperature (To) through a correction model to obtain an actual fluid outlet temperature (Tout); adjusting a heating power (Ph) of heating elements to keep the actual fluid outlet temperature (Tout) at a set reference temperature value (Tset). The correction model is an empirical model of a measurement error (E) derived from a plurality of experimental data sets, the measurement error (E) being a difference between the measured outlet temperature (To) and the actual fluid outlet temperature (Tout).
