The CO2 sensor option is transparently integrated into the core analyzer operation. All
functions can be viewed or accessed through the front panel display, just like the
functions for SO .

is measured with the motherboard and draws 12 VDC from the analyzer via the relay
card from which converts to fit the power needs of the probe and its own onboard logic.
It outputs a 0-5 VDC analog signal to the analyzer's CPU via the motherboard that
corresponds to the concentration of CO
