摘要： A measurement device for measuring a property of a fluid, in particular a concentration of a substance or an ion concentration in said fluid or a pH-value of said fluid, comprising: a housing comprising a housing section to be immersed into the fluid during measurement operation, and an aperture foreseen in an outside wall of the housing section, in particular in a side wall surrounding an interior of the housing section or in a front wall closing off a front end of the housing section, for exposing a single sensor for measuring the property of the fluid to the fluid, when the housing section is immersed into the fluid. This allows quick and easy replacement of the single sensor and characterizes in that, a number of at least two sensors for measuring the property are foreseen, each of the sensors is mounted in a different outside surface region of a movable mechanical support, and the mechanical support is movably secured inside the housing by means allowing for the support to be transferred into a number of different measurement positions, wherein in each measurement position a different outside surface region of the support comprising one of the sensors is exposed to the aperture.
