APM 433

Stand-alone equipment for monitoring inorganic gaseous pollutants with
Thermo- Electric cooling system to increase the efficiency of absorption

The APM 433 Gaseous Pollutants Sampler has been designed for monitoring Gaseous Pollutants like SO2, NO2, Cl2, H2S, O3, NH3 etc. in ambient air. The APM 433 is an independent stand-alone monitoring instrument (unlike our gaseous sampling attachments APM 411 and APM 411 TE that need to be paired with a dust sampler).
