Measurement device and measurement system

A measurement system, comprising:

• a substrate;
• a plurality of electrodes on a front surface of the substrate, wherein
• each electrode of the plurality of electrodes is configured to detect a potential in a solution;
• a sensing control circuit, on the substrate, wherein the sensing control circuit is configured to control the detection of the potential by each electrode of the plurality of electrodes;
• a temperature sensor, arranged on the substrate, configured to detect a temperature of the solution;
• a front surface side heat radiating unit, on a front surface side of the substrate, configured to radiate heat of the substrate;
• a back surface side heat radiating unit, on a back surface side of the substrate, configured to radiate the heat, wherein the back surface side of the substrate is different from the front surface of the substrate;
• a temperature control unit configured to control the temperature of the solution based on the temperature detected by the temperature sensor;
• a temperature adjustment unit configured to absorb the heat and radiate the heat to adjust the temperature of the solution based on the control by the temperature control unit;
• a shielding unit, between the temperature adjustment unit and the substrate, wherein the a shielding unit is configured to shield at least one component of the measurement system from the heat radiation from the temperature adjustment unit;
• and
• a processing circuit that is configured to process the detected potential.
