Model No. GAA-0001 · Air Quality Monitoring Equipment
紫外荧光二氧化硫分析仪
Air quality networks and fence-line programmes near coal plants and smelters rely on ultraviolet fluorescence for SO2, and this analyzer uses excitation at 214 nm. Detection limit is 0.4 ppb (2σ), with zero drift under 1 ppb per day. Pick the 0–500 or 0–2000 ppb range and the output type your station logger expects.
