摘要： A concentration correcting apparatus comprising a correction coefficient calculating means and a correcting means is shown and described. The correction coefficient calculating means calculates a correction coefficient for correcting the concentration of the material when the actual density of the medium at the measurement of the material is calculated in terms of the density of the medium under the reference temperature and pressure, from the results of the temperature measuring means and the pressure measuring means. The correcting means corrects the results of the material measuring means to a concentration under the reference temperature and pressure on the basis of the correction coefficient. The measure value of the material in the medium under constant temperature and depressure is virtually calculated by correcting the measured value by using the correction coefficient while calculating the volume of the medium which is regarded as a parameter of a temperature and a pressure in terms of a volume under the constant temperature and pressure. It is therefore possible to calculate the concentration per unit weight under constant conditions even if the temperature and the pressure are varied at the time of measurement.
