The invention relates to a measuring device for measuring a concentration of an analyte contained in a fluid, which comprises a probe (1, 5, 45) which can be submerged in the fluid and whose probe (1, 5, 45) comprises an amperometric sensor for measuring the concentration comprising the analyte contained in the fluid. The measuring device according to the invention also enables efficient detection of a pH of the fluid. For this purpose, the probe (1, 5, 45) comprising the amperometric sensor comprises a potentiometric pH sensor for the metrological detection of a pH value of the fluid. |
