The APSA–370 is a device for the continuous monitoring of atmospheric SO2 using UV fluorescence. The APSA–370 employs an proprietary, internal dry–method sampling device to achieve the highest levels of sensitivity and accuracy. The dry–method, due to its minimal maintenance requirements capability of continuous monitoring and instantaneous analysis of gas in its unaltered state, has been a preferred method for monitoring the atmospheric pollution.
