The RAC 3-Gas and 5-Gas Samplers are wet-chemical systems that sample ambient air for up to three or five different pollutant gases simultaneously. They feature a thermoelectric system for maximum accuracy in SO2 sampling and can be used for area surveillance, plant perimeter surveys, and interior air quality monitoring. The modular design allows for easy changes in sampling train configuration to meet variable sampling requirements.

The RAC 3-Gas Sampler is a wet-chemical system that samples ambient air for up to three different pollutant gases simultaneously and features a thermoelectric system to assure maximum accuracy for SO2 sampling.

The 3-Gas Sampler tests for sulfur dioxide (SO2), nitrogen dioxide (NO2), hydrogen sulfide (H2S), ammonia (NH3), aliphatic aldehydes (R-CHO) and other pollutant gases for which there is a suitable reagent (absorbing solution). This sampler can be used virtually anywhere that line power is available to serve widely diversified gas sampling requirements.

In its basic configuration, the 3-Gas system is designed to collect samples of SO2, NO2 and a third (optional) gas simultaneously. Modular components permit easy changes in sampling train configuration – except for the SO2 arrangement (Station 1) – to meet varying sampling needs

The 5-Gas Sampler tests for sulfur dioxide (SO2), nitrogen dioxide (NO2), hydrogen sulfide (H2S), ammonia (NH3), aliphatic aldehydes (R-CHO) and other pollutant for which there is a suitable chemical reagent (absorbing solution). This versatile instrument can be used to accurately sample a single gas or up to five different gases simultaneously. Simplified design, ease of assembly and modular components permit easy changes in sampling train configurations to meet variable sampling requirements.

The 5-Gas system can be used virtually anywhere that line power is available and is used for area surveillance, plant perimeter surveys and interior air quality monitoring or evaluation.
