  • Development of an SO2 monitor for mobile sources

    This high sensitivity requires that the monitoring beam pass through at least a few meters of sample gas. Thus, this imposes certain minimum limits on the size of the sampling volume. This limitation, in turn, requires a relatively high flow rate of the sample gas in order to displace the gas within the sample volume in the required
