SO2 & H2S ANALYZER MODEL VAIR-9001-VASTHI INSTRUMENTS (INC IGV) US EPA Reference Number EQSA-0225-267

El analizador de SO₂ Vair-9001 está diseñado para la medición precisa de concentraciones ultrabajas de dióxido de azufre en el aire ambiente mediante el método de fluorescencia UV. Una lámpara UV de alta estabilidad garantiza una sensibilidad constante, mientras que un avanzado sistema interno elimina la interferencia de hidrocarburos para obtener lecturas precisas.
