Abstract

PURPOSE: To improve a performance in calibration and measuring operation by adding a means for generating potential for offset adjustment which generates desired potential for both polarities of plus and minus and a 2nd amplifier which outputs a reverse signal for another amplifier.
CONSTITUTION: The means 21 for generating potential for offset adjustment and a means 22 for generating potential for calibration are provided, while the 1st amplifier 23 and the 2nd amplifier 24 generating a reverse signal for the 1st amplifier are provided and are connected to an indicator 27 through the intermediary of a variable divider 25. And, two standard liquids whose density is known are selected and by one of them the calibration of a standard value is performed, while the calibration of sensitivity is performed by the other. When the standard value is calibrated, the electromotive force of an ion electrode is negated by the means 21 for generating potential for offset and the output of the 1st amplifier 23 is made to be zero, while the value in the indicator 27 is adjusted to be the density of the 1st standard liquid by the means 22 for generating potential for calibration. Therefore, the standard value is not influenced by the calibration of sensitivity and the calibration can be completed by one operation.
