 With its dual detector system, the
LI-6262 analyser can measure simultaneously CO2 and H2O very
precisely and using the same optical path.The LI-6262 software
allows direct readout of CO2 and H2O vapor concentrations in units
of mole fraction, partial pressure, mass units, or dew point (for the water channel). It
is capable of RS-232C or analog output for both CO2 and H2O
measurements.
CO2 and H2O vapor measurements are corrected for
temperature and barometric pressure. Pressure can be entered from the keypad, through the
RS-232C port via an external computer, or by connecting an external pressure transducer to
an analog input channel. The analyser software can also correct CO2
measurements for dilution and pressure broadening by H2O vapor.
Recommended accessories for LI-COR gas analysers include the 6262-03 Pressure
Transducer, which allows corrections for barometric pressure fluctuations to be performed,
and the 6262-04 Reference Pump, used with the LI-6262 to purge H2O from the
reference cell during absolute mode operation. |
