The MEXA-1170SX is a continuous gas analyzer for sulfur compounds existing in engine emissions. It can measure SO2 concentration and the amount of total reduced sulfur compounds (TRS), such as H2S, separately. It can also measure the total sulfur compounds (TS) that contains both gaseous compounds and liquid compounds in PM, such as SO3. By utilizing ultra-violet fluorescence (UVF) method and various original analysis techniques such as ozone injection, the MEXA-1170SX achieves reliable measurements with low interference from other co-existing compounds.
