Abstract
An analytical device includes a heat output portion for heating an interior of a housing with which an analyzing portion is surrounded; a first temperature sensor for measuring a temperature of the analyzing portion; a second temperature sensor for measuring a temperature of an interior of the housing; and a control portion. The control portion determines a setting value of the temperature in the housing according to a transfer function of a PID control based on a difference between a preset temperature of the analyzing portion and the temperature measured by the first temperature sensor. Further, the control portion determines an output value of the heat output portion according to a transfer function of PID control based on a difference between the setting value of the temperature in the housing and the temperature measured by the second temperature sensor.
