Measure the amount of carbon monoxide (CO) in ambient air with the Thermo Scientific™ Model 48i CO Analyzer. The gas filter correlation technique as utilized by the Model 48i gas filter correlation analyzer offers over 30 years of field-proven performance in providing accurate and reliable readings.
The Model 48i is based on the principle that carbon monoxide (CO) absorbs infrared radiation at a wavelength of 4.6 microns. Because infrared absorption is a nonlinear measurement technique, it is necessary for the instrument electronics to transform the basic analyzer signal into a linear output. The 48i uses an exact calibration curve to accurately linearize the instrument output over any range up to a concentration of 10,000ppm.
