Abstract

The performance characteristics of commercially available sulfur dioxide monitors were determined.^Conductimetric, colorimetric, and coulometric analyzers were investigated.^During this phase of the study, characteristics that were more closely related to field operation were studied.^These included comparability of data among the instruments over a period of time, weekly calibration drift, maintenance requirements (including operating cost), unattended operation performance, and the effect of rotameter changes on calibration.^The methodology and apparatus used to determine each operational parameter are described.^The results of this study should be useful in the selection of instruments for monitoring sulfur dioxide.^5 references, 2 figures, 11 tables.
