A device for analyzing at least one parameter of a chemical or biochemical or biological reaction in a reaction container, the analysis device comprising:

• an arm intended to be fastened by means of a sliding link against a face of a wall of the reaction container by means of a static end, the arm having a degree of freedom in translation in relation to the wall of the reaction container, a sensor designed to measure the at least one parameter, the sensor being fastened to a free end of the arm,
• a drive device designed to cause an axial displacement of the arm along the degree of freedom,
• a hermetic isolating device for isolating the arm from the chemical or biochemical or biological reaction, the hermetic isolating device joining the arm to the face of the wall of the reaction container.
