The internal high-temperature converter can convert H2S under 315℃ without affecting other gases. After entering analyzer, sample gas first passes through SO2 remover(get rid of SO2 in sample gas) and then high-temperature converter to turn H2S into SO2. The concentration of SO2 can be detected via Ultraviolet Fluorescence method. The detection module detects sample gas that passes through control path and outputs continuously in form of analog signal.
The optional zeroing/calibration solenoid valve simplifies calibration by controlling calibration gas. The special auto zeroing function makes point more stable.
