3.2.2 For Use with Dedicated Sampling System
Piping is connected to the measurement liquid inlet and drain outlet. The piping will depend on the
sampling equipment. When the ST401G sampling system is to be used, refer to its instruction manual
IM12A0V2-E.
Figure 3.3 shows an example of piping for the ST401G Sampling System.
For details, refer to IM 12A0V2-E Sampling System.
