摘要:
A gas monitor for monitoring the concentration of particular atmospheric constituent includes a sensor and a signal processor that provides concentration-indicating output signals in response to successive samples admitted to the sensor. The processor multiplies the sensor signals by a calibration signal. It automatically recalibrates the monitor by periodically causing a sample having a standard concentration to be admitted to the sensor and adjusting the calibration signal to provide a corresponding predetermined output signal level.
