Note
Multiple rod electrodes which are connected
to several signal conditioning instruments or
a multiple channel instrument require an earth
rod to avoid influencing among the signal
conditioning instruments.
Double pump control
For a double pump control e.g. with EL 5 you
require a VEGATOR 532 Ex.
