ABSTRACT:
System and method for calibrating a sensor comprises a detector capable of detecting electromagnetic radiation at least at a radiation wavelength of interest, an analyzer capable of determining concentration values in response to the detected radiation, and a calibrator capable of automatically calibrating the analyzer in response to at least one concentration value. A method for operating a calibrator comprises receiving an initiation signal capable of initiating the calibrator, automatically obtaining concentration values in response to the initiation signal, and automatically determining a calibration value from the obtained concentration values. In an embodiment, the calibrator automatically determines when a calibration gas equilibrates within a sample chamber.
