2. A few words in advance

®
The Conex DIA-1 is a multipurpose device
designed to carry out high-precision measurements
and controls of pH value, redox potential, chlorine,
chlorine dioxide, ozone, hydrogen peroxide or
peracetic acid.
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.
®
The Conex DIA-1 combines the functions of exact
chlorine measuring and automatic pH value
compensation in one single device. For this purpose,
®
the Conex DIA-1 features a pH sensor interface
and an interface for external instrument amplifiers.
®
Properties of the Conex
and controller include the following:
• all control functions including PID and
continuous-action controls
• manual or automatic temperature compensation
• logbook function: chronological recording of
calibration values with date and time
• user coding function as a means of protection
against access by unauthorised persons and for
system administration
