The Bacharach 24-7224 Flue-gas Sample Conditioner helps removing water vapor from the flue-gas sample.
Since SO2 and NO2 are absorbed easily by water, it becomes imperative to remove moisture from the flue-gas sample for obtaining comprehensive and accurate data, especially for the purpose of emissions testing.
It is used in combination with the ECA 450 and helps in preventing formation of water droplets inside probe hose. If droplets of water form, part of your gas sample may become absorbed in the water, resulting in a lower than actual SO2 and NO2 readings.
The 24-7224 removes the water vapor passing gas samples through its Peltier Cooler to chill the sample, causing water vapor to become condensed. The water can then be pumped out from the cooler & into the water trap.
