Sample cell
It may be necessary to use the sample cell if the process (e.g. a pipe) is
too small for the DMP248 sensor head. Furthermore, if the process is
very hot (>80 °C) or particularly dirty, the probe is installed in a
sample cell behind a cooling coil and/or filter. In this case, the
ambient temperature must be at least 10 °C warmer than the process
dewpoint in order to avoid condensation in the sample tubing.
