Teledyne Analytical Instruments Model 2000A Thermal Conductivity Analyzer is a versatile microprocessor-based instrument for measuring binary mixtures of gases. Model 2000A responds to the differences in thermal conductivity between various gases by continuously comparing the sample gas with a reference gas of known thermal conductivity.
Thermal conductivity is inherently non-linear in certain applications.
To compensate for this phenomena, Teledyne has programmed the 2000A to automatically linearize the signal over the ranges and gases desired for analysis. 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.
