The PULSI 200LR is an ideal instrument for the emission monitoring of cement kilns. This in situ instrument is not only capable of monitoring up to six stack gas components but is also fully verifiable. This is achieved by manually or automatically flooding the in situ sample cell with a certified test gas, traceable to a national standard. Thus the CEM system can be shown to meet local Environmental Agency requirements such as US EPA 4OCFR Part 60 and 75.
