Abstract
PURPOSE: To improve the precision of measurement by automatically computing the saturated solubility on using the asymmetrical pulsating signal given by the temperature detector as it is.
CONSTITUTION: A signal, which is given when the change-over controller 9 operates, for example, the blower starts its operation, is fed to the arithmetic unit 11, 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 for the control period, the integral is divided by the control period to obtain the average temperature, and the value is displayed on the indicator 12.
