PROBLEM TO BE SOLVED: To monitor the concentration of a sterilant using a thermometer in a simple manner when the sterilant is charged into a decompressed sterilization chamber.SOLUTION: The concentration of a sterilant in a sterilization chamber is monitored which is calculated by a sterilization apparatus comprising a vacuum pump reducing the pressure of the sterilization chamber to a predetermined pressure, charging means for charging the sterilant into the decompressed sterilization chamber, a first temperature measuring part coated with a catalyst decomposing the sterilant to measure the temperature generated by decomposition reaction of the catalyst and installed in the sterilization chamber, a second temperature measuring part installed in the sterilization chamber to measure the internal temperature in the sterilization chamber, and calculation means for calculating the concentration of the sterilant in the sterilization chamber based on a difference between the internal temperature and the generated temperature measured after charging the sterilant into the sterilization chamber.SELECTED DRAWING: Figure 6 |
