Simply introduce your sample gas flow into the inlet of the Model 908 portable CO2 analyzer, and see results on the LCD within 15-20 seconds. The inlet accepts a flow rate of 50cc/min to 1000 cc/min. If you don’t have a source of flow or positive pressure, the analyzer can be equipped with an internal pump to draw in sample gas for analysis.
