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®DIA-1 measuring amplifier
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
• error message function for indication of
non-functioning sensors.

our customers.
5. Applications
The Conex®DIA-1 instrument amplifier and
controller is suitable for measuring chlorine (Cl2),
chlorine dioxide (ClO2), ozone (O3), hydrogen
peroxide (H2O2), peracetic acid, pH or redox
potential and for controlling these variables using
appropriate actuators within the applications
described in this manual.
6. Safety
6.1 Obligations of the owner/operations
manager
The owner/operations manager must ensure that
persons working with the Conex®DIA-1 instrument
amplifier and controller fulfil these requirements:
• They are acquainted with the regulations
concerning working safety and accident
prevention.
