Thermo Environmental Model 48C/H
Carbon Monoxide Analyzer


The Thermo Model 48 CO analyzer uses a gas filter correlation/non-dispersive infrared detector. The gas filter correlation technique reduces instrument cross-sensitivity to similar gases. Calibration values are adjusted via the zero and span thumb wheels or microprocessor (depending on the model). The Model 48C offers ranging up to 30,000 ppm and the Model 48H offers ranging up to 50,000 ppm.
