ABSTRACT:
An object of the present invention is to perform measuring work easily when detecting the presence or absence of an object to be measured or the concentration thereof using a plurality of quartz sensors equipped with a Langevin type quartz resonator. As a concrete means for solving the problem, a quartz sensor3equipped with a quartz resonator30forming an adsorbing layer to adsorb a target component to be measured on one surface side and coming into contact with an airtight space on the other surface side is installed in a printed circuit board4via a base5. A plurality of quartz sensors3is detachably installed respectively in a plurality of connecting terminal units provided in a horizontal arrangement on a side surface21of the measuring device main unit2via a connecting terminal unit41formed on an end of the printed circuit board4in a state that the above-described adsorbing layer faces upward. The measuring device main unit2includes an oscillation circuit71electrically connected to the quartz sensor3, detects the variation of the natural frequency of the quartz resonator due to coming the sample solution into contact with the above-described adsorbing layer, and measures at least one of the presence of the target component to be measured or the concentration of the target component in the sample solution based on the detection result.
