This paper discusses the development, evaluation, and field performance of a device designed to provide accurate sulfur dioxide concentration standards suitable for auditing the accuracy of continuous, ambient SO2 monitors. This compact, lightweight, device has been subjected to extensive testing and found to be a reliable and accurate SO2 audit system. A discussion of the evaluation and acceptance testing as well as the results from two years of field audits is presented.
