RAC 5- Gas Sampler
Portable Wet Chemistry System for Collecting Pollutant Gases
The RAC 5-Gas Collecting Sampler is a wet-chemical system that samples ambient air for any pollutant gas in which there is a suitable chemical reagent (absorbing solution). The Sampler tests for sulfur dioxide (SO2), nitrogen dioxide (NO2), hydrogen Sulfide (H2S), ammonia (NH3), aliphatic aldehydes (CHO) and other gases reactive to specific chemical solutions. This versatile instrument can be used to accurately sample either a single gas or up to five different gases simultaneously. Simplified design, ease of assembly, and modular components permit modifications of sampling train configuration to meet variable sampling requirements.

The RAC 5 Gas sampler is used for area surveillance by numerous state, county and federal government stations, as well as international projects associated with the World Health Organization. RAC's 5-Gas Sampling System is available as an all-weather shelter model, furnished complete and ready-to-operate. It is fabricated from heavy-gauge steel, has a heavy-duty baked enamel finish, and is suitable for use under all climate conditions.
