DESCRIPTION The Nova 423 Series Carbon Dioxide monitor/controller has a sensitive solid-state infrared CO2 detector which continuously displays detected CO2 on a front panel digital meter. A built in sample pump draws in a sample through a filter and flow meter then on to the solid state infrared detector for analysis. A 4-20mA linear output signal is available for operation of a recorder or input to a computer. The Model 423 CO2 Monitor can be time shared between a number of sample points using a Nova automatic sequencer. Calibration need only be done once per year. Applications include...
