CO2 GAS MEASUREMENT SYSTEM FOR A LABORATORY INCUBATOR

摘要

A gas measurement system (10) for measuring the concentration of CO2 gas in an incubator (12) includes a radiation source (20) for radiating energy; a reference detector (22) operable to receive a portion of the radiated energy, to detect a spectral range of the energy outside of an absorption band of the gas, and to generate a signal representative thereof; a sample detector (24) to detect the spectral range of the energy within the absorption band of the gas, and to generate a signal representative thereof; and a control assembly for comparing the signals generated by the reference and sample detectors to determine the concentration of the gas in the enclosed area.
