The model SA-633 utilizes UV Fluorescence method. Predominant spectrum of Zinc lamp at 214 nm excites sulfur dioxides. The excited molecules of SO2 releases their energy as fluorescence light emission when they fall in the ground state. The emission light is detected by a photomultiplier tube. The lamp intensity monitored continuously is used for the compensation to gain accurate value. Aromatic hydrocarbons are removed by a hydrocarbon remover. |
