We introduce and solve a model of a thermometric measurement on a driven glassy system in a stationary state. We show that a thermometer with a sufficiently slow response measures a temperature higher than that of the environment, but that the measured temperature does not usually coincide with the effective temperature related to the violation of the Fluctuation-Dissipation Theorem.
