Stack Diluting Sampler Overview:
The stack diluting sampler is an easy to use device that provides accurate pre-dilution of high temperature gas emissions with nitrogen or zero-air to minimize condensation inside the sample bag. Dilution is achieved inside the heated probe and can be controlled from 1:3 to 1:305 in 14 steps.
If hot gasses emitted from a stack are directly placed in a tedlar or nalophan bag they begin to develop condensation. These small droplets of water absorb many of the critical components that contribute to the overall odour of the sample. The stack diluting sampler eliminates this problem by mixing the stack air with dry clean Nitrogen so that the moisture can’t condense inside the bag. The mixing happens inside the probe and since the probe becomes at the same temperature as the stack air, there is no chance of the sample developing condensation before being mixed with Nitrogen.
Stack Diluting Sampler Basics of Operation:
Attach sample bag
Open valve on the nitrogen micro tank
Select the desired dilution from 1:3 to 1:305 bu, while installing the corresponding dilution disk
Insert the probe into the stack and allow 3 minutes for it to reach the same temperature as stack gases
Press the trigger and wait for the sample bag to fill
