When the dew point of a process needs to be measured using DM70, the process can be sampled using one of the following devices:
- DSC74
- DSC74B
- DSC74C
- DSS70A
- DMT242SC
- DMT242SC2
Use the DSC74 sampling cell when the sample is taken from the pressurized process, where the process pressure forces the sample gas into the sample cell.
Use the DSC74B sampling cell as DSC74. DSC74B is enhanced version of DSC74. With version B, harmful gases can be recovered.
DSC74C complements DSC74B with a diffusion coil, which allows measuring in the atmospheric pressure.
Use the DSS70A sampling system when the process is not pressurized, that is, the sample must be pumped from the process and when the process is dirty or too hot for direct measurements.
Use the DMT242SC sampling cell when only the body (thread 3/8"G and 1/4"G) of the main sampling cell is needed.
Use the DMT242SC2 sampling cell with the welded Swagelok connectors. This is ideal for sampling in a 1/4" pipeline.
