Abstract
PURPOSE: To improve the precision of measurement by automatically computing the saturated solubility on using a signal given by the temperature detector as it is and b avoiding the cooling of a fixed temperature or less when cooled.
CONSTITUTION: A signal, which is given when the change-over controller 11 operates, for example, the blower starts its operation, is fed to the arithmetic unit 21, a time interval between the instants at which the signals are introduced, that is, a control period, is computed an output signal of the temperature detector 6 is integrated, the integral is divided by the control period to obtain the average temperature, and the value is displayed on the indicator 22. Also an output of the temperature detector 6 and the lower limit setting signal are fed to the comparator 23 the output of which controls the number of turns of the blower.
