紫外光度臭氧分析仪
Summer smog studies, crop exposure research and regulatory ozone stations all depend on stable 254 nm UV photometry. This analyzer reaches 0.5 ppb detection with 0.25 ppb RMS zero noise and 95% response within 20 s. The manganese dioxide scrubber is replaceable on site. Choose 0–500 or 0–2000 ppb to match your station type.
