<p>A measurement instrument (2) mounted on a concentration measurement apparatus (1) for performing concentration calculation according to concentration calculation information and capable of outputting concentration calculation information to the concentration measurement apparatus (1). This measurement instrument has an attribute information output unit (28) capable of outputting attribute information related to the attribute of the measurement instrument (2) as an electric physical amount. The attribute information is assigned according to at least one of the conditions: a resistance value of the attribute information output unit (28), a formation part of the attribute information output unit (28), and a formation region of the attribute information output unit (28). The attribute information is used, for example, for selecting a detection ray appropriate for the measurement instrument (2). The attribute information may relate to a particular measurement reference applied to the measurement instrument (2).</p> |
