Model 48i Carbon Monoxide Analyzer

Key Features

  • Gas filter correlation technology
  • Linearity through all ranges
  • Standard dual range and auto ranges
  • Measures concentrations up to 10,000ppm
  • Temperature and pressure correction

Description

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.
