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.
Discover the iQ to work smarter with our next generation 48iQ Carbon Monoxide Analyzer.
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.
The Mode 48i CO Analyzer is also available with an oxygen sensor module.
The Model 48i with Oxygen uses paramagnetic sensor technology to extend CO measurement capabilities, reading and reporting the concentration of oxygen in the sample stream up to 100%. Additionally, programming allows the user to correct the CO reading for the amount of oxygen in the sample.
