Measuring device and measurement system

Abstract

The measuring device 40 includes: a measuring flow path L2 connected to a flow path L1 for supplying the measuring liquid as the object of measurement or a container for storing the measuring liquid, wherein the measuring liquid flows due to the pressure of the measuring liquid itself in the flow path L1 or the container; an electrochemical measuring unit 41 disposed in the measuring flow path L2 for performing electrochemical measurement of the measuring liquid; a calibration liquid flow path L3 connected to the measuring flow path L2 located upstream of the electrochemical measuring unit 41 for supplying calibration liquid for calibrating the electrochemical measuring unit 41; and a calibration liquid supply pump 42 disposed in the calibration liquid flow path L3 for supplying calibration liquid to the electrochemical measuring unit 41. A Measuring Device 40 includes: a measuring flow path L2 connected to a flow path L1 through which a measurement liquid serving as a measurement object flows, or to a container in which the measurement liquid is stored, wherein the measurement liquid flows due to the pressure of the measurement liquid itself in the flow path L1 or the container; an electrochemical measuring unit 41 provided in the measuring flow path L2 and performing electrochemical measurement of the measurement liquid; a calibration liquid flow path L3 connected to the measuring flow path L2 upstream of the electrochemical measuring unit 41 and through which a calibration liquid for calibrating the electrochemical measuring unit 41 flows; and a calibration liquid supply pump 42 provided in the calibration liquid flow path L3 and supplying the calibration liquid to the electrochemical measuring unit 41.
