e-Series Sulfur dioxides Analyzer SO₂

AF22e dilution

UV Fluorescence gas monitor offering excellent performances for the monitoring of SO2 in the range 0-10 ppm or 0-1 ppm

Eco-designed, reference air quality monitor, QAL1 certified by the TÜV, US-EPA approved. Utilizes the standard method for the measurement of sulfur dioxides(EN 14212). With its ultra low power consumption & 24 V supply (option), the AF22e is the sole SO2 monitor on the market able to measure without being connected to the power grid.

Add to Compare
