2. A few words in advance
The Conex
®
DIA-2 is a multipurpose device
designed to carry out high-precision measurements
and controls of the following:
•
a value from parameter group 1:
– chlorine, chlorine dioxide, ozone or hydrogen
peroxide
• a value from parameter group 2:
– pH value.
The integrated controller, the high-resolution
graphics display and the multilingual plain-text user
interface make complicated measuring and control
tasks in water chemistry much easier.
Just a few button inputs lead you to your goal. The
potentiostat helps save even more time, being
automatically matched to the various input variables.
The safety standard of the dosing process is raised
by the automatic open-circuit monitoring of the
current outputs.
