Calibration method and zirconia-type oxygen analyzer using this method |
摘要 |
A calibration method in which secular change in sensor output values obtained at calibration times is estimated and the next calibration date can be determined at an appropriate interval and a zirconia-type oxygen analyzer using the above calibration method is achieved. The present invention is characterized by the fact that, in a calibration method in which a standard sample having a known value is measured and the output value of a measuring instrument corresponding to a sensor output value at the time of measurement is calibrated, the sensor output value obtained in implemented calibrating operations is stored in succession as the data for calibration history and the state of secular change in said sensor output value is estimated based on the stored past data for calibration history to determine the next calibration date.
