Abstract: A method and apparatus for calibrating a sensor for determination of the concentration of a sterilant, e. g., hydrogen peroxide vapor, in a sterilization system. This invention provides a method for calibrating a sensor that is used for measuring the quantity of a sterilant in a system for delivering the sterilant, the method comprising the steps of: (a) generating reference calibration data, the reference calibration data showing a mathematical relationship between a measurable parameter, e. g. voltage, and a quantity of the sterilant, e. g., parts of sterilant per million parts of air (ppm), for a plurality of sensors; (b) generating sensor calibration data, the sensor calibration data showing a mathematical relationship between the measurable parameter and the quantity of the sterilant for an individual sensor; and(c) normalizing the sensor calibration data to compensate for the difference between the measurable parameter for the reference calibration data and the measurable parameter for the sensor calibration data, whereby data obtained by the individual sensor can be used to accurately determine the quantity of sterilant in the system.
