ENVEA - Multi-Gas Dilution System

Ideal for mid-high to high concentrations or for sampling locations in hazardous areas. The flue gas is extracted, filtered & diluted with clean / dry air, by an in-stack dilution probe, before being sent to the analyzer. This technique lowers the flue gas dew point, keeping the sample temperature above it and at ambient temperature, in order to eliminate all condensation issues (water interference-free). This also reduces the risk of contamination of the analyzer (low concentrations). The dilution allows sample measurements in highly corrosive, dirty or high concentration conditions. The diluted sample is transported in an unheated sample line to the analyzer. This reduces the overall cost of operation of the system.
