Abstract
Sulfur dioxide, at concentrations of 40 ppm to 1 percent in the off gas of an so2 removal system, must be monitored continuously in the presence of normal atmospheric gases and combustion products. An inexpensive and reliable conductivity cell using h2o2 as the absorbing reagent is used to measure so2 concentrations at less cost to the user than commercial instruments currently available. The instrument and systems for controlling the liquid and gas flows to obtain reproducible and reliable measurements of so2 concentrations are described.
