In addition, the unit is programmed to provide 110 customer selectable gas combinations for easy use. Three field programmable ranges are standard on Model 2000A plus a calibration range. Optional ranges for use with different background gases are available. Although Model 2000A is primarily used to analyze binary mixtures, this instrument is also well suited to monitor one component in a more complex mixture when the other gases have the same ratio to each other, or have similar values of thermal conductivity. Automatic linearization Auto Ranging automatically selects the proper preset range for a given measurement.
Manual override allows the user to lock onto a specific range of interest.
