An electrogustometer comprises an interface (4) capable of receiving a stimulation instruction, and a current generator (8) arranged to produce a stimulation current. The interface (4) is arranged to obtain a digital command from the stimulation instruction, and the electrogustometer further comprises a digital-to-analogue converter (6) suitable for converting the digital command into a DC voltage, the different digital commands inducing discrete respective voltage values. The current generator (8) is arranged to convert the DC voltage into a stimulation current with a strength of between 0 and 250 µA, depending on the discrete voltage value, and varies by fixed steps of between 0.05 µA and 1 µA.
